Thanks Grant. So let me see if I understand...I need *both* payMethod-CC and card-VISA+MC. How do I do that if I'm only accepting credit card payments to begin (shoppers don't have option of invoice, etc.)? Can it be done with an additional hidden input to the form? Can you give an example (I'm afraid I'm not too good at this yet!)?
