Please,
At this stage there is no possibility to update to a newer version. All complex conditions are made. Only problem at randomization remains ...

After this study will put the new version 2.0.
Please, there must be a way. I tried this script, but not activated.
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
// Identify this question
var qID = {QID};
// Place the "DK" code option at the end of the list
var answer = $( 'input[id$="X'+qID+'DK"]');
var answerItem = $(answer).closest('li');
var answersList = $(answer).closest('ul');
$(answersList).append(answerItem);
});
</script>
Please tell me how to change it for this version.
Many many thanks!
