I am a little confused when richard populates the orderdetail sub-form in the orders form. He puts a different product price in the orderdetail to the product price in the product table ie gives a discounted price. Is the discounted price stored in the orderdetail table and overwriting the existing product unit prices and then richard creates a product table later with its own product unit price field further complicating me as this is in its own table. In the orderdetails it not simpler to tie the product unit cost from order table and product unit cost from orderdetails table both to the newly created product table putting a drop list in orderdetails unit cost field referencing unit cost in products table and adding a discount field in orderdetails form to apply the unit price reduction but maintaining the actual product unit price also. Im just confused as to what is or is not bound and if bound, bound to what.
