That didn't work either, but examining the process with my boss (who is doing the testing) the browser never goes to checkout_success.php. It goes directly from cart_static.php to checkout.php to https://secure.authorize.net/gateway/transact.dll. I believe we set it up to skip the billing and shipping intake pages because Authorize.net collects that information. We went through some hoops to make that work and Jason did some direct editing, which is why I didn't want to go back thru the checkout wizard to set up the detailed email receipt. We want the customer, but even more important OUR client to get the transaction details from the eCart rather than Authorize.net, as they control how much info comes thru and how it is presented.
