• Last Name - Verify first character is a capital letter and that there are 1 to 49 characters (may include spaces and special characters.
• Address Line 1 - Verify that there are 1 to 49 characters which may include spaces and special characters.
• Address Line 2 - Verify that there are 0 to 49 characters which may include spaces and special characters.
• City - Verify first character is a capital letter and that there are 1 to 49 characters (may include spaces and special characters.
• State - Verify that it is capitalized two letter state abbreviations as defined by the US Post Office.
• ZIP - Verify that it is either a 5 digit ZIP code or a 5+4 ZIP code.  Both types of ZIP codes should pass.
• Phone Number - Verify that it is a legal US phone number.  Allow muliple entering fomats so that the user could enter (320) 555-1212 or 320-555-1212 or 320.555.1212 or even 3205551212.
• Email - Verify that it is a legal email address.  Remember there are new Top Level Domain (TLD) names that are up to 6 characters long.
• Year Born - Verify that the year born is from 1900 to 2022 inclusive.
• Form should not submit if there is an error with one of the fields.

Once built and published, test your form.  All input fields will be echoed back if your form is working correctly.
