As I pointed out in my earlier post the grid() method 
returns None

Thus if you want to keep a reference to the widget you have 
to create it and then pack() or grid() it.

Just like that....

Hmm, I did point it out last week in my original response...

The Tkinter introduction also majkes the point explicitly

in section 3 "More on widget references"

I recommend Tkinter beginners go through this tutor.
