I don't think you are....

Says that self.code is a 'nonetype' object, not a text box.

You are storing the retirn value from the grid method in 
self.code.  But the return is none.

You need to separate the steps:

self.code = Pmw.EntryFoeld(self.root)
self.code.grid(....)

IMHO Its a shame the layout manager metjods don't 
return self but they don't so you have to use a two 
stage approach if you want to keep a handle to the 
widget...
