Combo Box validation in Outlook 2000

I have a combo box with several values for a user to choose from a dropdown list and I want to limit the user to selecting one of the values in my list. However, it appears that I tried to use too many characters in my Validation Formula because Outlook simply truncated my validation formula string. Is there an easier way to limit the user to only selecting from a choice in the list other than doing a validation formula like this:[ListName] <> "A" or[ListName] <> "B" or[ListName] <> "C" or[ListName] <> "D"?

Have you looked at the "MatchRequired" property in the Advanced Properties
of the combo box? If you set that to true, the user must select from the
list of options.
