I get the following error a lot. Most of the orders go through fine.

"The transaction resulted in an AVS mismatch. The address provided does not match billing address of cardholder. - Your credit card could not be authorized for this reason. Please correct the information and try again or contact us for further assistance."

I understand that Zen Cart checks the billing address versus the Credit card info and kicks the error back when they are not Exact! Is there a way to set the cart so that it only varifies the zip code or CCV number and not the entire address?

Thanks
