Jason,
I got it to work. I had the eCart Bindings incorrect. Also when using Tom Muck's Dynamic Search Suite (search/results) you have to have the "Add to Cart" button on the page before applying the Tom Muck Dynamic Search Suite. Tom's extension modifies the name of the recordset to TomListRecordset and then it is not available for selection within the eCart dialog.
Appreciate the help. THnx. D
