Hi everyone,

This little glitch is driving me crazy and I hope someone can point me in the right direction. I've been through everything I can Google in the groups and documents on this topic, but nothing seems to be working.

Simply, I want to update the value of a hidden question from an previous group based on responses from subsequent group questions. The final group has an equation question that runs the code below. I have to do this in script.

It seems so simple...but the values never stay and never update in the database. I've tried using plain numeric input questions and an equation type questions. nada ...

This is probably so obvious that I'm going to be embarrassed... :blush:


 
$(document).ready(function() {
   var T = 100;
   $('input#answerSSXGGXQQ').val(T);   //previous groups question
}
</script>

Hello,

With a short text question, try:
$("#question{QID} input.text").val(T);

AND you loose e ); at the end. Please see your javascript console log.

Denis

PS: look at tpartner answer too.

You can't use JavaScript to modify the value of a question from a previous group. JavaScript can only modify elements in the current page.

Cheers,
