@NetworkNerd said: If I understand correctly, that code snippet is only for a validation that will be run against the Phone1 field. Are you just trying to throw up a validation error on a web page or within an application if a proper phone number is not entered in the PHONE1 field? He wants to extract out the first 10 digits of the PHONE1 field and present them to the application / page as the phone number so that the native regional formatting of 10 digit TN handles it correctly.
