Field Validation allows you to accept only the data that meets your required format. Here are the predefined validation types available for the Basic (free) service plan:
Text Box: none
Website: URL (web page)
Phone: numeric (3-3-4)
However, you cannot change the validation of a form field on the Basic plan. To do so, you’ll need to upgrade to Gold or a higher plan. We also provide more complex field validations for paid plans, which you can customize according to your needs.
