I am using the Authorize.net SIM Module. everything seems to work correctly except the fact that when i place an order in test mode. it appears to work but returns my to OScommerce stating: The credit card transaction could not be verified with this order. Please try again and if problems persist, please try another payment method. Although OSC says it could not be verfied, i recieve an e-mail reciept from authorize.net stating that the order was processed. any help would be appreciated.
