hi Mr. Miyoshi,
thank you so much for taking time to respond.
Aside the fact, that I’m trying to do exactly what you are suggesting, the validation won’t throw an invalid message, even in initial state. When the answer to the quiz is incorrect the form only shows a general ‘One or more fields have an error. Please check and try again’ so I’m not sure it works when I implement a custom validation.
Sorry, I’m sure i’m overlooking something, could you point me in the right direction?
kind regards
chris
