My mind is rusted and I cant come up with exact tables, their relationships, PK/FK and then forms and a subform. Any help would be appreciated. Can someone point me to a simple structure to able to make a simplest invoice using combo boxes to pull an item and make total with taxes on the bottom; dont need to store customer or shipping address etc info, but will record daily / weekly sale. If you know a site where I can find a template ( Not Northwind), please write the URL, thanks everyone...<br />
