i am looking to set-up a basic dvd rental system where by i have a list of the dvds, list of the customer details and then a table listing the rentals. i want the database to work whereas a customer rents a dvd, the rental is then added to the rental table and the availability of the dvd is changed from yes to no in the dvd table. when the dvd is returned i then want the availability to change back to yes and the customers rentals to delete the rental from their list. it should be pretty simple but i am really struggling at how to figure out how it works. been quite a while since i last used access so any help is very much appreciated. thanks.
