I have done a sample checkout in the Cart. Have registered having an account (not a guest), supplied billing info, shipping info and credit card information. The transaction appears to process. But I receive a notification from credit card company (authorize.net) that not going through. It appears that the shipping address is not being transmitted to the credit card gateway. Is there something I need to "turn on" in payments extension to allow info to get through. Any insight will help. Thanks.
