I have a IPN response script that uses the "custom" variable that was posted in the initial form request , which contains the username of the payee. The first payment will send the variable no problem but will it continue to send the same variable each month the payment is made? If not, is there a variable I can use that will keep it stored and sent each month?
The basic idea of what I'm trying to accomplish: http://pastebin.com/552u7QTG
