Everything seems to work with Discover and American Express cards but there is an issue with the Visa and MasterCards. According to authorize.net it's the format of the information being passed and because of this these cards are being declined. It's the same info as is being passed for discover/amex and I can't seem to find documentation indicating where I am going wrong. Any ideas?

Thanks!!!

Make sure that you are passing in your information in the format:

CCProcessPayment(

merchantAccount;

transactionKey;

chargeAmount;

cardNumber;

expDate

)

You may want to use a data viewer if you have FileMaker Pro Advanced to make sure that the information you are passing in for each of those parameters is correct. You may have a variable which is not being passed in properly.
