It looks like Dreamweaver wasn't able to connect to your database when the checkout wizard ran. That caused the insert into the database code to be incomplete on the pp_confirm.php page. I've removed the save in database code and the page now works properly.
You will either have to run the wizard again (make sure the database connection works before running) or you could just apply the two server behaviors "Store Cart Summary in Database" and "Store Cart Details in Database" on the pp_confirm.php page, since those are the missing elements.
