Не производятся вычисления в программе

я ОЧЕНЬ начинающий программист. Не производятся вычисления при нажатии на кнопку. Как это починить и почему. Гайды смотрел, не помогло. Заранее спасибо за помощь.

Вот, код программы, написан на Питоне.

from tkinter import *

root = Tk()

ost1 = 0
ran1 = 0
pot1 = 0
ost2 = 0

pot2 = 0

helper = [0,0,0,0,0,0]
# Остаток
if ((block * numbers * bonus) — (damage1 * numbers1 * bonus1)) / block ⇐ 0:
ost = 0
else:
ost = ((block * numbers * bonus) — (damage1 * numbers1 * bonus1)) / block

# раненные
if ((block * numbers * bonus) — (damage1 * numbers1 * bonus1)) / block ⇐ 0:
ran = numbers * 0.2
else:
ran = (numbers — ((block * numbers * bonus) — (damage1 * numbers1 * bonus1)) / block) * 0.2

# потери
if ((block * numbers * bonus) — (damage1 * numbers1 * bonus1)) / block ⇐ 0:
pot = numbers — numbers * 0.2
else:
pot = (numbers — (((block * numbers * bonus) — (damage1 * numbers1 * bonus1)) / block)) — (
(numbers — ((block * numbers * bonus) — (damage1 * numbers1 * bonus1)) / block) * 0.2)
