In this Microsoft Access tutorial I'm going to teach you a few things to try to speed up lookups (DLookup, DSum, DCount, etc.) in your Microsoft Access database

Lucas from Chino Hills, California (a Platinum Member) asks: I don't know why one of my forms is loading so slowly. It's basically my customer list, but I need to look up their sales rep from the employee table based on their state. The form ran fine before I added the DLookup, but I really want that information on there. What should I do?
