Hi, my app has a menu to register a participant. Is there a way to put a warning message like ‘You have registered’ whenever the same participant try to register again? Tq (btw, this in logon environment using email add.)

You could create a Show column into your table structure showing that warning text. Formula like IN(USEREMAIL(),TableName[Email]) could check is that user already registered or not.
