        print(self.button, type(self.button))
        print(self.textEntry, type(self.textEntry))
        print(self.co, type(self.co))

I really don't know, if you print the type of self.button you get that
it's a "string", same with self.co. I will look into the code that
does the lookup for the value, somehow it's getting replaced with the
key for the table?
