A family of Microsoft relational database management systems designed for ease of use.
If you have that information entered in a table, then you don't need to have Access AutoEnter that information. It CAN be DISPLAYED using a query or you can have a combo box to select the city and have some UNBOUND text boxes display the selected values. But you don't store them in with the rest of the record.
See my sample here for how to include extra fields to display in a form.
