Hi - I'm setting up a cart in OsC 2.3.1 that uses only authorize.net for payment. I've installed and enabled the authorize.net credit card AIM and configured the login id, the transaction key, and the md5 hash code. When I go to the storefront and log in as a customer and proceed through checkout, when I get to payment informatiaon on the the checkout-confirmation.php page there is no option to put in whether my card is visa or mc. When I do enter a name, card number, exp date, and cvc code and click on confirm order, I get the error "Please try again and if problems persist, please try another payment method." Can you help me figure out what I'm doing wrong? Thanks.
