TIA,The validation is performed when you set payMethod=CC. Setting card=xx will further restrict card types to those listed. And yes, I think it's important to use this validation, because it prevents a lot of mis-typed entries by giving instant user feedback rather than waiting for the 'problem' email.Grant Hulbert, V.P.
