Hello.i am doing a stock management system for a cafe.i have a stock,sales and reorder form.In my reorder form i have the primary key field as a comb box which displays a value based on a query that shows which items have to be reordered.So this combo box displays the item name
So for example Pepsi and coke need to be reordered.After i first select coke and reorder it first and save and then do Pepsi i want the combo box to not display coke but only Pepsi as coke has already been ordered.What should i do?
