I need to calculate a shipping efficency. I have two sets of data, OrderDate and ShipDate, I need to Figure out how long it took each order to ship. Essientially I need to minus the Ship date from the Order date in a new field, entitiled "DaysToShip ". I'm new to access, so thank you for the help!!

P.s. If you need more information or I'm not being clear please let me know.
