Must Answer not enforced on Web Survey


Respondents can skip questions marked as “Must Answer ” in SurveyPro.

More Information

This is almost always the result of the “Enable This Server Must Check” box not being marked on the Answer Test screen during the publish to NetCollect process.  It is important to note that there are two ‘Must Answer’ conditions in the SurveyPro family.  Another configuration issue is described here.

If you have discovered this during the testing phase, you may simply republish while marking this box for each appropriate question.

If, however, you have already gone live with the survey and noticed this after the fact, you will want to make sure that you remove this condition on the Data Cleaning Screen during import so that the rule is not enforced locally (thereby rejecting records for respondents that skipped the question).

jQuery Sliders and SurveyPro

For this function we are going to use the jQuery Javascript Library

Step 1: Set up SurveyPro Survey

In order to create a slider, you are going to need to set up a question in SurveyPro that we can manipulate after we have published the survey.  The slider is just a fancy way for the user to put in a number in a text box, so slider questions will need to be set up with a scale of short written answer.  We’ll add the slider and adjust it’s placement after we’ve published our survey.

On page two of my survey I will create a question “How much do you like Ice Cream?” and give it the scale of “Short Countable written answer”.

Save and publish your survey per usual.

Step 2: Download jQueryUI

After you have published your survey, we will need to install the jQuery UI Library and place it on your server.

First download jQuery UI (User Interface) from their website:  This is a library of code that works with the main jQuery JavaScript file. This library contains code that will easily allow us to create animations, widgets, and other effects.  This is where the code for our slider exists.

By default have all of jQuery UI elements selected to download.  You can download all of them (we will use some of them later), or just download the ones we need for the slider, “UI Core” and “Slider”.  These will download as a zip file.

Open and extract the files in the zip.

For ease, go ahead and rename the folder you downloaded (it will default to something long, like “jQuery-ui-1.7.1.custom”).  Let’s just call it “jQuery”.

Go to the area of your server where you store the “Content” or front end of your survey of your projects.  This is where we are going to place the jQuery UI folder we just downloaded.  Copy the entire folder you just named “jQuery” and place it at the same level as the content side of your survey.

Step 3: Make Edits to SurveyPro ASP files:

Now we will need to make alterations to the asp page that contains the question(s) you will need to turn into a slider.

First we will need to call three files (Core, Slider and the main jQuery javascript files) from the JQuery UI bundle.

In the header of the asp page indicate the directory of your jQuery folder.  In Surveyhost surveys the directory looks as follows:

<script src=””></script>
<script src=””></script>
<script src=””></script>

Next you’ll need to attach the style sheets to the asp page.  These make the slider look like a slider.  These style sheets are contained in the development bundle folder (jQuery > development bundle)

<link rel=”stylesheet” href=”” type=”text/css”>
<link rel=”stylesheet” href=”” type=”text/css”>

Before we call the javascript function, include this small amount of styling to for the placement of your slider.

<style type=”text/css”>
#demo-frame > div.demo { padding: 10px !important; };

Then we will place the code for the slider function, also in the head of the asp page:

<script type=”text/javascript”>
$(function() {
min: 0,
max: 500,
slide: function(event, ui) {
$(“#amount”).val(‘$’ + ui.value);
$(“#amount”).val(‘$’ + $(“#slider”).slider(“value”));

This function is for a basic horizontal slider.  For further documentation on steps, minimum and maximum values, and ranges feel free to go to the jQuery documentation on their website:

Now, go down to the question that you want to add the slider to.  In my survey, the code for my question looks like this:

<td width=”350″ valign=”top” class=”pad-bkgnd-2″>
<span class=”question-1″>How much do you like Ice Cream?</span>
<td width=”300″ class=”pad-bkgnd-2″>
<div align=”center”><input name=”Q0002S001W” type=”text” size=”9″ maxlength=”200″ class=”ncauto-input-text”<%=NC_TextHidden(“Q0002″)%>></div>

What we want to do is add the slider (<div id=”slider “></div>), and make it so that the slider will report a number to our input field (id=”amount”)

<td width=”350″ valign=”top” class=”pad-bkgnd-2″>
<span class=”question-1″>How much do you like Ice Cream ?</span>

<td width=”250″ colspan=”3″ class=”pad-bkgnd-2″>
<div id=”slider “></div>

<td width=”100″ class=”pad-bkgnd-2″>
<div align=”center”><input name=”Q0002S001W”  id=”amount” type=”text” size=”9″ maxlength=”200″ class=”ncauto-input-text”<%=NC_TextHidden(“Q0002″)%>></div>

That’s it!  Give your survey a test, and feel how a creative user interface can effect the quality of your survey data.

How to create a quick Poll with Results in SurveyPro.


A tutorial about how to make Pop-up web polls with SurveyPro. It includes a sample file to download and the steps to create one from scratch. These are useful for getting visitor participation on your website and helping engage your audience.

The survey programming is pretty straight-forward. The coding of the pop-up aspect, however, requires some knowledge of HTML and basic web-programming. We don’t cover the pop-up part other than to mention which tools where used in the Demo.


Essentially, we need to create a survey which contains a single page.  On that page we would have the question(s) and the “Vote” button.  Exiting from that page would pull up the “Instant Online Report” page to show the results of the poll.


Pop-up poll questionnaire

Pop-up poll questionnaire

Create a questionnaire - Usually, polls are a single question, though there is no limitation in SurveyPro regarding this. It is important to keep dimensions in mind since iframes should have defined dimensions and the survey AND report will need to fit within whatever you set. Depending on which options you set for the Instant Report, 300px is about the minimum width you should use. You will likely need to experiment with this since you can set the width of the questionnaire, but not the report. You may also want to change the “start new” button text to “Vote!” or “Submit” (Document -> Properties -> Buttons Tab).

Page List Dialog

Page list dialog

Remove extra pages – This survey should be a single page, so remove any others (including “thanks” page) in the Document -> Edit Page List dialog.

Report login dialog

Report login dialog

Create the report – Go to Document -> Web Survey Setup, and click the “Edit” button next to Online Reports. Edit the Login Page (or create a new one) and make sure “No Password” is selected.

In the Edit Report dialog, select what stats you want to show.

Exit settings dialog

Exit settings dialog

Change exit settings – Document -> Web Survey Setup, and click the “Edit” button next to “Embedded Operation”. The report url will vary based on where your survey is hosted.


The “pop-up” aspect involves some knowledge of HTML. For our demo, we used a JavaScript library called jQuery and a plugin for jQuery called Thickbox. The intent is to pop up a modal window (i.e. an ‘iframe’) containing the survey. The survey itself could be hosted on QuestionWeb or your own server.

Another method, that is a little less “standards compliant”, is to pop-up an actual new window with javascript. We don’t recommend this method, though it is available.

Finally, another popular option is simply embedding an iframe in your HTML page and having the survey appear there.

One important thing to note – certain users’ networks disallow iframe content, particularly when the content comes from a different base url or server. This may be an issue if you use a survey hosted on questionweb.

Error Configuring a New On-Line Survey Project


You get a message that is similar to the following: (note, this affects all versions of SurveyPro from 3.0 forward)

One or more survey or report files expected for this project were missing or published at different times, specifically:
“file name”.st3.
Unable to proceed with setup.


This issue is caused by a SurveyPro specific file that was created before the Congressionally mandated change in the timing of Daylight Saving Time.  The file in question, StlCvt09J.dll, creates a date-time group that is embedded into the .ST3 file associated with the project.  The issue stems from the fact that the date-time group is one hour off and as such, NetCollect will refuse to publish the project.

The solution is quite simple.  The SurveyPro Development Team created a revised DLL which needs to be downloaded from our web site, unzipped and copied into the Program sub-directory where the SurveyPro executable resides.

The direct download for the file is After downloading the file you should unzip it to your desktop.  Once you are ready to copy the file you should locate the Program directory specific to your version.

In SurveyPro 3.0 the default directory is C:\Program Files\Apian Software\SurveyPro 30\Program\

In SurveyPro 4.0 the default directory is C:\Program Files\Apian Software\SurveyPro 40\Program\

At this time please ensure that SurveyPro is not running.  Once you have located the correct directory you should find and rename the file from StlCvt09J.dll to StlCvt09J.old.  This step allows you to quickly revert should something else go awry.

After renaming the file simply copy and paste the unzipped file from your desktop into the Program sub-directory.

After you restart SurveyPro you will be required to republish any projects that demonstrated the error message.  The .ST3 needs to be recreated along with the rest of the files set.
