@jjenglert @austinyang @pbs I have a similar case as the requests above. I have a form where I’m storing the record id of another block in a hidden field and want to pass the hidden record id in the Open External URL field of the On Form Submit Action. I’ve tried several pieces of code but keep getting an Error 400 - doesn’t seem to be picking up the hidden field recordID. Can some one help with the right code or url syntax? Something like: https://www.villageconnect.life/service-calendar?recordId={hiddenFieldValue}?
