When I am in the field name in field properties, I want a list box but I
can't remember how to populate the list to choose from.
Don't confuse data *storage* - fields which have datatypes - with data
*display* (listboxes, combo boxes, etc.).
Most developers strongly discourage the "Lookup Field" misfeature in
Access: see
http://www.mvps.org/access/lookupfields.htm for a
critique. I'd suggest simply making the table field a Date/Time field,
if that's the datatype you want; use a Form to enter data into the
table, and if desired, put a Listbox or Combo Box on the form. That
listbox's Row Source can either be a Query listing the dates you want
available for selection, or you can set it to List of Values and type
in the dates you want available (which of course may pose a problem as
time goes on and these dates become obsolete).
