The page: waue_customer_order_success.php has a bunh of include with absolute paths. You must have done a save as at some point and had dreamweaver update the paths?
I think you can just delete lines 1-8 from that file.
on the customer-order-status.php you are referring to a recordset defined on the page "rsOrders"
In order to do that you have to declare it as a global on the top of the page... just add this:
<? global $rsOrders; ?>
