You define entry in the local namespace of laggtillspare() and then try 
to reference it from bekraftspelare(), where it is neither local nor global.

That's why most Tkinter-based designs define a class for each window. 
The instance's namespace can then be used by all methods as a shared 
namespace. Instead of entry you would refer to self.entry in two methods 
of the same instance.

If you don't know what I'm talking about, take a look at some simple 
Tkinter examples. It should start to make sense after you've pored over 
the code for an house or so ...
