What's wiser, use the lookup wizard for a field and enter the three values I
want to offer users, or create a combo box and lookup the values from a
seperate table?
Neither.
Users should never see table datasheets, with or without lookup
fields.
Use a Form; on the Form you can put a combo box. It can be based on a
List of Values or a table as you see fit; the advantage of a table is
that it is easier to edit (say, to add a fourth value or change the
content of one of the values). The advantage of a Value List is that
it clutters your database less.
