    How to require 10 digit phone number

    Asked by agagsupport on May 04, 2017 at 11:24 PM

    Is there a way to require 10 digits be entered when a phone number field is filled in? We offer three phone number fields, cell, home and work so don't set the field as required.

    You can achieve that with Short Text entry (Text Box) field and setting Input Mask.
