Hello again Dr. Byte.
First off thank you for reply to my duplication problem. Will research into it now that I have a clue.
Modified the whos_online.php as directed and ran another test in debug mode. This time the return page was successful and returned me to the website saying the sale was successful BUT the items ordered are still not showing up in the invoice for customer viewing nor for admin viewing. The products ordered is 0. It still only shows the total and the shipping and the final amount. Here is the debug log for this second round:
