Hi

I need some assistance, why my code which i create in excel 2003 can't
run in
excel 97?

General work flow of my code.

I have a raw worksheet containing my raw data & a summary worksheet
which i want to show the information for a vol number. The user will
select from a drop down list the vol number in the summary worksheet.
The vol number is unique.

My code is working in excel 2003, but when i open it in excel 97, i
can't get the output which i want when i select a unique vol number
from the drop down list.

My code

Option Explicit
Sub Worksheet_Activate()
Dim LRow As Long
Dim rng As Range
Dim rng2 As Range
Dim ws As Worksheet

Set ws = Worksheets("raw")
Set rng2 = Range("B3")
LRow = ws.Cells(Rows.count, 3).End(xlUp).Row

' Set rng = ws.Range("C2:C" & LRow)
Set rng = ws.Range("B2:B" & LRow)

'rng.Name = "cid"
rng.Name = "volser"

With rng2.Validation
.Add Type:=xlValidateList, Formula1:="=volser"
End With

End Sub

Sub Worksheet_Change(ByVal Target As Range)
If Target.Row = 3 And Target.Column = 2 Then
'calculate criteria cell in case calculation mode is manual
Worksheets("summary").Range("B3").Calculate

Worksheets("raw").Range("data") _
.AdvancedFilter Action:=xlFilterCopy, _
CriteriaRange:=Sheets("summary").Range("B2:B3"), _
CopyToRange:=Range("A10:DD10"), Unique:=False

End If
End Sub

Thank you
