I have a combobox on a userform that pulls it's values from a named range

The named range references 10 cells formatted as dates, which contain the
formulas starting in cell A1:
=today()
=A1-1
=A2-1
etc.

When I click on the combobox, I get the dates listed in date format. When I
select one, the combobox populates with the /numeric/ date value.

I tried the following snippet, but because I require matching=true, the
combobox won't accept the changed format (invalid propery value):
Private Sub cmbDate_Change()
cmbDate.Value = Format(cmbDate.Value, "mmm-yy")
End Sub

I'm sure there must be a way to do this (Excel 97 and higher). Worst case
scenario, I suppose I can make the list text before I pull it into a named
range, but isn't there a better way? There doesn't appear to be a way to set
the format of a combobox directly....

Thanks in advance,
Keith
