Hello



I am making a database for a ordering system, however i am stuck in trying to do a function which i am sure Ms Access can do.



i am trying to do an order form where someone will order 20 items and if ten of the item is delivered first i want user to be able to type into a form that they have received ten of the twenty ordered. then when the next ten have arrrived i want users to go back on the same form and be able to type in ten delieved again but the sub total can calculate the previous ten



can anyone help me with this



thank you
