How can I create conditional formatting denying a response that isn't correct?

Hello,

I am creating a form for wedding RSVP. I am using a lot of conditional formatting so that users start by entering postal codes and then it unlocks a unique journey for however many guests they are allowed.

I want to create a rule where if someone enters a postal code that isn't on our list, it asks them to try again. Is this possible? Closest I could find was enable/require and disable submit, but that would require them to go through all questions first.

Thank you,

Michael

We don't have such a feature. You would have to create a condition to evaluate each postal code in your list, so if the postal code that is entered is different, then you could hide the submit button and show a warning, example:
