Question

Is there a way to ensure that the data entered into a field on a Form matches a pre-determined set of criteria? For instance, can I ensure that a phone number entered into a "Mobile Number" field has 10 digits, or that the data entered into an "Email Address" field is indeed an email address, and not something such as a home address?
