1.- Go to restrictions, and check “Limit the number of times the same value on a field can be submitted”.

Select the fields that you want to have this restriction

Configure an error message, this message support tags

And that’s it! Now the form will validate that the field doesn’t exceed the limit and if so it will show the configured message
