I am new to using both tkinter and python, and I am trying to create a GUI window thing that calculates the total cost of a date night, with different options for travel, entertainment, etc. I am having two major problems: 1. If the user attempts to enter a tip, nothing happens. The program works as long as the user does not try to leave a restaurant tip, though. I have tried reformatting, but I cannot seem to figure out why the way I have coded my tip isn't working. The tip is only supposed to be added if the restaurant option is selected. 2. This error is probably relatively simple, but I cannot figure out how to code a proper "quit" button. I have a few lines of code, which are my attempt to make a quit button after searching for solutions online, but I still seem to be missing something.
There is quite a bit of code, but I'll paste it here. I appreciate any advice or feedback :)

Also, I apologize for the weird comments that I put throughout. I deleted most of them, but I was tired when I made this and I thought everything was funny.
When I run code then I see error message which shows where is the problem and what is the problem. You should read it and think what wrong in this line. And you should also add this error message in question.
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python3.7/tkinter/__init__.py", line 1705, in __call__
return self.func(*args)
File "<pyshell#1>", line 14, in calc_cost
before_tax = travel_result.get() + entertainment_result.get() + dinner_result.get + ((int(tip_result.get()) / 100) * dinner_result)
TypeError: unsupported operand type(s) for +: 'int' and 'method'
Error shows line
before_tax = travel_result.get() + entertainment_result.get() + dinner_result.get + ((int(tip_result.get()) / 100) * dinner_result)
and in this line you forgot () in first dinner_result and you forgot .get() in second dinner_result
It should be
before_tax = travel_result.get() + entertainment_result.get() + dinner_result.get() + ((int(tip_result.get()) / 100) * dinner_result.get())
and now it shows correct result for Restarunt
As for button Quit - you forgot () in app_window.destroy()
def close_window():
app_window.destroy()
