I am using the stock "Order Entry" database that ships with Access. It works for my situation. The only thing I need is to beable to choose whether or not the items in the products table are taxable or non-taxable. I am not a programmer but can follow instructions well. I have added a taxable (yes/no) field to the products table. How do I get this information to properly calculate in the Order Details sub-form and ultimately on the Invoice report?
