How do I fix "local variable 'money' referenced before assignment?

Question

So I was making an Idle Miner-type game, and I’m trying to make an upgrade. When I wanted to make it so that when you buy said upgrade, your money goes back to zero, but then I got the error. I had it before, so I put global money. I thought this would fix it, and it did for a bit. Here’s the code

import time
import math
money = 0
amount = 1
print("Upgrades will occur at:")
print("10 dollars")
print("50 dollars")
print("100 dollars")
print("100 dollars")
print("1000 dollars")
print("10,000 dollars")
print("1,000,000 dollars")
print("")

def gm():
  global money
  money = money + amount
  print("You have " + str(money) + " dollars!")
  time.sleep(1)
def m():
  while True:
    gm()
    if money == 10:
      upg1 = input("Would you like to buy a multiplier? y for yes, n for no ")
      if upg1 == "y":
        global amount
        amount = amount + 1
        print("")
        print("ACHIEVEMENT!: Baby's first upgrade")
        print("")
        money = 0
        time.sleep(2)
      else:
        print("You will have a chance to buy this again :)")
m() ```

As @Random Davis pretty much said, the only problem is that you forgot to include global money at the top of function m similarly to how you included it in gm.

Also I recommend positioning global amount outside the while loop in the function m to optimise you program, ensuring that the keyword global won’t have to be called repeatedly, as it is a relatively resource-expensive keyword.
