Problem with variabels in Tkinter

[Svennglenn]

I have a problem with a program i'm
making in Tkinter.
The code is avaliable at:
http://paste.plone.org/943

When i'm running the program and enters a value and press the
button in the dialog window that comes up when a press the
button "Lägg till spelare" (add a player in swedish)
I get this error message:
NameError: global name 'entry' is not defined



Does anyone know what the problem is?
