3 random numbers out of 5 was created by exlibris69
Hi guys,
does anybody know how is it possible to display 3 random numbers out of 5 in one (!) equation question? For the moment I use equation which displayes 1 number {if(is_empty(Q1ran),rand(1,5),Q1ran)} and now it should be increased to 3 figures.
Hope somebody can help me.
Thanks in advance.

Do you just want to show these number or want to do something with them? . We can suggest something if you can let us know little more what exactly you want to achieve in survey.

I'm not sure you can do that in one equation question but using JavaScript, you could load three sub-questions of a multiple-short-text question with 3 random numbers out of 5.
Set up your survey to use JavaScript and add the following script to the source of a multiple-short-text question (I think the comments explain what's happening):

<script type="text/javascript" charset="utf-8"> $(document).ready(function(){ // Identify this question var thisQuestion = $('#question{QID}'); // Hide this question (un-comment below) //thisQuestion.hide(); var numbers = [1,2,3,4,5]; // A function to shuffle elements or contents of arrays (function($){ $.fn.shuffle = function() { return this.each(function(){ var items = $(this).children(); return (items.length) ? $(this).html($.shuffle(items)) : this; }); } $.shuffle = function(arr) { for( var j, x, i = arr.length; i; j = parseInt(Math.random() * i), x = arr[--i], arr[i] = arr[j], arr[j] = x ); return arr; } })(jQuery); // Shuffle the array numbers = $.shuffle(numbers); //Load the first three array values and fire Expression Manager $('input.text', thisQuestion).each(function(i) { $(this).val(numbers[i]); checkconditions(this.value, this.name, this.type); }); }); </script>

For the moment we have a question of products categories consumption. There are 5 categories, which should be evaluated. Each category has block of nearly 20 questions. Respondent can chose up to 5 categories. In case the respondent chose 4 or 5 product categories he should evaluate 3 of categories he knows randomly. Now it's a problem to prescribe conditions for all groups of respondents - to be exact, for those who chose up to 3 cat. and should evaluate all 3 and for those who chose 4+ and should evaluate randomly 3 of 4 or 5.

x= max number of products to rate.
hq = hidden multi question;
steps:
#Copy punches in hq using EM.
#Randomize answer list of hq.
#Keep top x and clean all other using javascript
#Use hq in array mask of desired question.
