I'm sorry to keep posting here without waiting for an answer... But I've actually figured out how to do the other suborder tables. Basically I setup two more table that have the same relationship as `orderdetails` does with `orders`, and I'm storing the engraving and accessory "product attributes" in the new tables. This works great, but I still need to resolve the issue where it takes hitting the "Update" button several times to do all of the calculations. Unless there is a way to "Edit" one item in the cart by pulling all of it's attributes into a "recordset" os sorts.
Thanks for your patience.
