There's information here on Excel 97 data validation and worksheet events:

Hi

I am using the following code to enable multi select from drop down
lists in XL2003, but have a group of users requiring this feature in
XL97...


Public InActivity As Boolean

Private Sub Worksheet_Change(ByVal Target As Range)
If InActivity Then Exit Sub
InActivity = True
On Error GoTo NonValidatedCell
If Selection.Validation.Type = xlValidateList Then
ColAbs = Target.Column
If ColAbs < 3 Then GoTo NonValidatedCell
RowAbs = Target.Row
If Sheets("Recreation_Activity").Cells(RowAbs, ColAbs).Value = "Delete
Contents" Then
TotalString = ""
Else
Application.Undo
TotalString = Sheets("Recreation_Activity").Cells(RowAbs,
ColAbs).Value & ", "
Application.Undo
TotalString = TotalString &
Sheets("Recreation_Activity").Cells(RowAbs, ColAbs).Value
End If
If Left(TotalString, 1) = "," Then TotalString = Mid(TotalString, 3)
Sheets("Recreation_Activity").Cells(RowAbs, ColAbs).Value =
TotalString
End If
InActivity = False

Exit Sub
NonValidatedCell:
InActivity = False

End Sub


The spreadsheet opens in XL97 without error but you can only select
one item from the list...
Selecting a second item just overwrites the first..

Any suggestions??????
