Hate to do this. . .
The fallfest_orderID session value is not passing back after the return from the payment processor. If I simulate it using localhost it works fine. However using the hosted site the value is null. . .
Same FTP login credentials will work. . .
Thanks, Jason. . .
ETA -- hosting company tells me that the session issue is probably because I'm using a shared IP. So I tried adding a cookie to payment.php saving $_SESSION['OrderID'], which is available on payment.php. However the cookie doesn't seem to be writing because it's not available on the finalize.php page which is the return page from the processor. payment.php attached.
ETA2. Played some more -- the cookie is writing, but not being read by finalize.php -- attached. . .
