Dim noDupes As New Collection
Dim rw As Long
Dim itm As Variant
Selection.AutoFilter Field:=3
rw = ActiveSheet.AutoFilter.Range.Row
For Each cell In ActiveSheet.AutoFilter.Range.Columns(3).Cells
If cell.Row <> rw Then
On Error Resume Next
noDupes.Add cell.Value, cell.Text
On Error GoTo 0
End If
Next
For Each itm In noDupes
