Paste this code:
   If Target.Cells.Count = 1 And Target.Column = 16 Then
      Target.Offset(, 2) = Target
      Application.EnableEvents = False
      Target = ""
      Application.EnableEvents = True
   End If
Below the row:
Private Sub Worksheet_Change(ByVal Target As Range)
and above the row:
End Sub
