If you are trying to do this as part of a table definition, be aware that
lookup data types in tables can cause confusion (see John's response). Also
be aware that Access 2007 uses a new file format, .accdb (see Gina's
response).
If you intend to have users interacting directly with the table, stop now!
Access tables store data, Access forms (and reports) display data.
