In need of help!

Does anyone know how I could change the code below to reference to B13
in stead of B2..?
It filters info in column A to Column B which works fine but I need it
to start the filtered list at B13.

(I've tried everything!)



Private Sub Worksheet_Change(ByVal Target As Range)
Dim myRow As Long
If Target.Cells.Count 1 Then Exit Sub
If Target.Column < 1 Then Exit Sub


Application.EnableEvents = False
If Application.CountIf(Range("B:B"), Target.Value) = 0 Then
Range("B65536").End(xlUp)(2).Value = Target.Value
End If


For myRow = Range("B65536").End(xlUp).Row To 2 Step -1
If IsError(Application.Match(Cells(myRow, 2).Value, Range("A:A"),
False)) Then
Cells(myRow, 2).ClearContents
End If

Next myRow


Application.EnableEvents = True

End Sub
