I am sending the following value to paypal from my buy it now buttons: <input type="hidden" name="return" value="http://www.vitalrec.co.uk/processorder.php?order_id=12345678"> but when it comes back from a valid sale, paypal seems to cut off the variable part and goes to: http://www.vitalrec.co.uk/processorder.php anyone experience this, and know how to make it work right?
