   Do While ActiveCell <> ""
      If FirstItem = SecondItem Then
        ActiveCell.Offset(Offsetcount,0).Interior.Color = RGB(255,0,0)
        Offsetcount = Offsetcount + 1
        SecondItem = ActiveCell.Offset(Offsetcount, 0).Value
      Else
        ActiveCell.Offset(Offsetcount, 0).Select
        FirstItem = ActiveCell.Value
