On to the next challenge
I rebuilt both my catalog and cart php pages. I set up recordsets for each product using a filter with the product_id number as the value. When I set up the cart in display manager, I made sure to indicate thumbnails to display as images and browsed to the folder containing the thumbnails.
I configured my add to cart buttons as dynamic not static and simply let the lightning bolts do the work.
I tested everything and voila! Thank you for your help.
