Note though, that the sequential number will increment with every respondent, even those who don't complete the survey.

Add this script to the source of a short-text question:

Code:

<script type="text/javascript" charset="utf-8">  
 
  $(document).ready(function() { 
 
    var submitID = {SAVEDID};
 
     // Hide this question
    $('#question'+qID).hide();
 
    // Find sequential number between 1 and 4 based on the SUBMITID
    var conditionNumber = (submitID % 4) + 1;
 
     // Load the hidden question
    $('#question'+qID+' input.text').val(conditionNumber);
  });
</script>

.

I don't know where to fill in this script?
After the first page submission.... So after the first question is filled in, by the second question fill in this script? Of by the first question, after the page with welcome and intructions? And how do i make the different questionaires for the three groups?

Place the script in the source of a short-text question on a page AFTER the first QUESTION PAGE has been submitted.

I need your help.

I have two different questions and I want the survey tool to show one question at a time randomy. I want to assign my participants to the survey randomly. That is why I used the equation question type with rand(1,2) function. The test survey works perfectly. But when I activate it, it stuck on one condition and only shows the same question for everytime.

Do you know why it happened??

Thanks a lot.

Kind Regards,

Probably not relevant anymore, but maybe some desperate limesurvey user will read this and rejoice:

Create a Question (myQuestion) of Type Equation. Set the Question Text to
This will assign a random value between 1 and 4 to myQuestion, if it has not been previously assigned.
