We were able to get these issues corrected in a screen sharing session.
The issues were all related to the cookie based shopping cart.
1) we had to add session start code to the success page because the cart wasn't automatically starting the session to get the orderID to display
2) we had to add an iframe to the bottom of the page to clear the cart from the cookie from another page. Because cookies are saved and removed in the page header, we couldn't do it on the bottom of the success page itself.
