I'm sending x_version=3.1 but still BLANK CVVresultcodes with card code
as 901 to produce an error.field 39 ???I'm receiving in XML and there is
no 'field 39'.//response/CVVResultCode is still always BLANK.
I can get specific AVS testing responses by using the 'zip-code' but I
can't get any card-code responses by using the 3-digit card-code for CVV
testing???The cvv response is always 'blank'.I've made sure to not send
an address or a zip-code thinking ...
