    Can I make sure people enter a 10 digit telephone number?

    Asked by jmarks244 on March 31, 2017 at 03:48 PM

    Is there a way to validate data before it is submitted? Specifically, I want to make sure people enter a 10 digit telephone number.

    I examined your form and found that you have properly configured input masks for your phone number fields, so I understand that you have sorted things out?

    If you need further assistance please let us know. We will be happy to help. Thank you.
