We are up and running. I redid the page and authorize.net processed it.
However, I never saw the checkout_success.php page. So, how do I get the customer to a page where they do their download.
Attached is the page I'm seeing.
I assume the TEST MODE thing is on the authorize.net side, because it didn't charge my card. (I'm about to contact them as to how I get out of TEST MODE.) Is the TEST MODE thing any reason as to why I didn't see the checkout_success.php screen?
