Sometimes there is a requirement to validate email addresses to ensure they are entered in the correct format. Simply go to the 'Field Details' tab within FormMaker for the Field, and open up the 'Data Constraints' section.
Cut and paste the following value into the 'Pattern (regular expression)' field:
[0-9A-Za-z'\.\-_]{1,127}@[0-9A-Za-z'\.\-_]{1,127}
This pattern will ensure that the email address is less than the maximum size and contains a valid pattern of characters.
