Hello,
I am interested if there is a way to prevent submitting the form twice if the lead already exists (for example based on email as a unique identifier)
and if possible showing the corresponding message
thank you

There are unique fields (email is default) allow merging contacts

and that’s exactly what I am trying to avoid -merging a contact because when you merge you overwrite the old data in the fields with new data.
In my situation, when a new contact enters his email I grab some extra referral data and if he comes back again and enters the email again the original referral data gets overwritten with the new referral data and I don’t want that… So I either I need to prevent submitting the form if the contact already submitted it once or somehow lock the fields if they are populated already

Any solution on this? Subsequent submitting of a form overwrites the existing data…
