When I did this it eliminated all the new fields i had added. There are 3 folders to choose from in the bindings tab of the ATC button when I click the lightning bolt: Perhaps I chose the wrong one? They are "boh", which I believe is the cart object, "boh_4_ATC_tags_double", and "Validated Entries". I chose the "boh" folder, in which each field has a lightning bolt next to it.
I am beginning to think i need to start over and rebuild this ATC from scratch!
