I have this code :-

Private Sub CommandButton1_Click()

Dim FW As Variant
Dim rngCell As Range

FW = Worksheets("LU").Cells(1, 1).Value

With Worksheets("Detail")
Set rngCell = .Cells.Find(What:=FW, _
After:=.Cells(1, 1), LookIn:=xlValues, _
LookAt:=xlWhole, SearchOrder:=xlByRows, _
SearchDirection:=xlNext, MatchCase:=False)
End With

If Not rngCell Is Nothing Then
MsgBox rngCell.Row
End If

End Sub

Worksheets("LU").Cells(1, 1) contains value "109435"

When running I get error "Run-time error 1004 - Unable to get the Find
Property of the Range Class"

Any ideas?
