Hi Klas!
Ok, so I am not the who did it wrong, ok, I will report it to the tracker.
I have enabled the brigde.
I placed all my fileds on one filed, the user goup assignment worked, but when I tried to do it with conditional states it did not.
The field got the value, but it was not saved, so I could make it work with a javascript code:
jQuery('#statusz').click(function(){
var num= jQuery(this).val();
jQuery('#user_groups').val(num);
});
This way it works fine.
Thanks for your support and replies!
