Problem: When a customer attempts to checkout with the wrong CC information or insufficient funds, they progress to the checkout confirmation page and then they are sent back to the checkout payment page with no error when they confirm their order.
I'm trying to add a define parameter in this array for the gateway_services_cc.php file.
My objective is to create a generic credit card error message for users that enter in the incorrect card number or when their card is declined due to insufficient funds.
I have a good idea on where and how to implement the code, I just don't know how to create the variables that would define the error so that Zen can pick up on it and que the error message.
Any help you can provide would be much appreciated as always.
