Im having a problem with my payments for my corecommerce store and i wondered if you could tell me how corecommerce retrieves post variables from the post method, or at least the file which i could find to find this out.

Also seperate note but would anyone know why my custom payflow module would send the expiry date as 'EXPDATE' => '02W{', and not just 'EXPDATE' => '0212'. Its a long shot me asking but any asumptions might help me figure it out.

many thanks
