TEMA:

YES! I just made it. I was about to write a similar question

I created the form, and edited the "Send" button with a libraryscript (FF_validate_submit). And then I chose to edit the ENTIRE form (not any of the buttons/items in the form). In there I put a library script (ff_nextpage). And that's it.

"All out of the box, it works, young Padawan"

I have tried your solution but it didn't work, since I don't have the option ff_nextpage available. If i copy the script from the library it doesn't seem to work... Any other solutions??

Are you editing the entire form or a single entity in the form (eg. a textfield or a button)?
