OnSubmit Actions don´t work

Hi,
I am using the latest Version of ChronoForms v4 in Joomla 1.7.2.
I can not get the OnSubmit Actions of my form to work.
I put an email Action, a store Data, and even a debugging action in the form, but none of them work.
Is there any setting I might missed?
Thanks in Advance!

Hi StingerMKO ,

Have you set an On Submit URL in the form General tab?

Please take a Form Backup using the icon in the Forms Manager and post it here (as a zipped file) or PM or email it to me and I'll take a closer look.

Hi Bob,
thanks, this was the hint I needed.
I set an OnSubmit URL. Now it works.
Kind regards,
Malte
