I would like to see what

        self.low_clutter_val = self.clutter_low.GetPosition()

        self.high_clutter_val = self.clutter_high.GetPosition()

low and high clutter val are (can you print them, as well as their type, eg

  print low', type(self.low_clutter_val), self.low_clutter_val

and likewise for the high val.  From the error, it looks lik they are
not scalars.
