Hello, I am putting together a small database to store orders, part of this is to specify card payment on the order form (I am assuming a customer may have several cards). I would like to have a dropdown menu that will show the cards that have already been entered for the customer. I have tried to use a lookup, but the resulting dropdown menu will show all the cards that have been entered, I would like just to show the cards for the specific customer.
I would very much appreciate your help on this.
This is for academic purposes - I dont need to worry about actually storing card detail.
Thanks
