I signed up for a regulatory compliance course from Penn State. When entering credit card (Visa) details, the year of expiry i.e. 20 or 21 is not insertable. For example if the expiry date is Aug, 21, it should be entered as 08/21, but when I try to enter the date it writes it as 08/22 (last digit automatically shows one ahead). If I try to enter say using the preceeeding number so that the date shows online correctly (example type 08/20 so it shows as 08/21), it still gives an error.
