i am pretty new to this and having a hard time figuring out how to validate a phone number answer. the question is, "what is your phone number?" the response is a numerical input field, the max is set to 10 characters. i want to be sure they enter a 10-digit number (no hyphens).
currently, if an invalid number is entered, it just disappears and the survey moves on without them knowing they didn't enter a valid number. i definitely don't want this to happen.
i have looked at the EM section of your manual but haven't been able to get this to work the way i'm hoping.
thank you in advance for your assistance! oh, i have version 1.92 if that matters.
