If youhave your system set up properly, the user can change the quantity when-ever they like and your price gets changed appropriately.I'm guessing that you have some sort of volume discount and you areconcerned that a smart user will order 1000 then go back and change itto 1, yet still get the 1000-unit price.Create a loop at the top of your invoice page, after they have the chance to change the quantity but before they complete the purchase.Use a [lineitems] loop and reset the price based on the quantity in thecart at that time. This way, even if they go back to the shopping_cartpage and adjust the quantity, you will always have a chance to correctthe price.You can also do the price update at the same time they perform changethe quantity. Remember that when changing the price, you need to use aprice-change password. It is not a security issue because it is a context rather than a command (the user never can see the password).John PeacockGlenn Busbin wrote:> > I'm having a problem passing a [quantity] field to Invoice.tpl.
