Isn't that for the Payflow gateway though?
I know the direct payment with credit card won't carry the details, but I thought the Express checkout part would.
Clicking on "Pay with PayPal" is an Express Checkout...right? This account has both.
Also, on the checkout.php page for the generic cart example, I viewed source and I don't see where the item details are passed.
BTW. Were you able to login to the ftp provided?
