i downloaded version 3.5 of the form and when i created a form it worked ok. Then i decided to add a little more functionallity using radio and checkboxes. Unfortunatelly it didn’t work!
When i decided to check the source code i saw that the function doAddLabel(…) is using this: _dhxForm_isIPad = (navigator.userAgent.search(/iPad/gi)>=0); which was commented.
I removed the comment and now it is working like a charm!
In case somebody else is having this problem now you know how to fix it:)
