I would like to make a balance entry widget, which will accept only integers, and value must be 20 - 5000. I have made only int criteria, but i have no idea how to handle with 20 - 5000 value limits.
I tried to make a "Start game button" which execute if statement, but it does not update the value which i typed in entry box, it has 0 by default at the beginning, even if its it command function of a button.
If someone knows a solution please give me a hint!
@EDIT: Whole my code below!

Second EDIT:
@Mike - SMT many thanks for a help! I revised my code with your instructions, I noticed that i need to put self. to image variables to make it works. After all of the corrections code looks like below, i have a question regarding gaining window properties from MainApplication Class, i put there method 'window_properties()' and run it also at TopLevel window but it does not get its properties, do you maybe have some idea how i can get it without placing the same code at toplevel wind? (without method it also not getting proper size of it)
Also, please tell me how i can get 'self.player_name' and 'self.player_balance' values in MainApp Class now?
Solution: I have changed this lines FirstWindow() into self.first_window = FirstWindow()
and now i can get to this values by self.first_window.player_balance and now it works.
EDIT: I reduced not necessary code.

What you are doing here is overkill. By separating everything into different classes you are making it harder to get to variables in different classes. though possible I would build your top window all in one class instead of many.
That said I would also build your main application to inherit from Tk() instead of Frame().
I have removed your images for testing functionality of the below example.
Consider the below reworked code and let me know if you have any questions:
