My code is not working out for some reason. But when I don't open my file in a function it will work. So I need help opening a python file in my menu file. Here is the code:
first file:
from tkinter import *
def Game():
    mult = 1
    clicks = 0
    clickgame = Tk()
    clickgame.geometry("500x500")
    clickgame.title("Techno Clicker")
        
    def buttonCommand():
        global clicks
        clicks += 1*(mult)  
        clickslabel.config(text=clicks)
    def multiplyerX1():
        global clicks
        global mult
        if clicks > 99:
            clicks -= 100
            mult += 1
            clickslabel.config(text=clicks)
        else:
            lickslabel.config(text="Not Enough clicks")
             
    def multiplyerX5():
        global clicks
        global mult
        if clicks > 499: 
            clicks -= 500
            mult += 5
            clickslabel.config(text=clicks)
        else:
            clickslabel.config(text="Not Enough clicks")
    def multiplyerX10():
        global clicks
        global mult
        if clicks > 999:
            clicks -= 1000
            mult += 10
            clickslabel.config(text=clicks)
        else:
            clickslabel.config(text="Not Enough clicks")
    Background_btn = PhotoImage(file="/Users/PrivateInfo/Desktop/ClickImage-3.png")
    clickslabel = Label(clickgame, text="0 Clicks")
    clickButton = Button(clickgame, image=Background_btn, command=buttonCommand, borderwidth=0)
    clickmultX1 = Button(clickgame, text="Buy Click Multiplyer x1 (Costs 100C)", command=multiplyerX1, padx = 10, pady = 5)
    clickmultX5 = Button(clickgame, text="Buy Click Multiplyer x5 (Costs 500C)", command=multiplyerX5, padx = 10, pady = 5)
    clickmultX10 = Button(clickgame, text="Buy Click Multiplyer x10 (Costs 10000C)", command=multiplyerX10, padx = 10, pady = 5)
    clickslabel.pack()
    clickButton.pack()
    clickmultX1.pack()
    clickmultX5.pack()
    clickmultX10.pack()
    clickgame.mainloop()
Second File:
from tkinter import *
import os
import sys
import ClickingGame
mult = 1
clicks = 0
menu = Tk()
q = 0
def firegame():
    global q
    ClickingGame.Game()
TitleLabel = Label(menu, text='Welcome To Techno Play')
GameLabel = Label(menu, text='Games:')
ClickingGameButton = Button(menu, text='Clicking Game', command=firegame)
                            
TitleLabel.pack()
GameLabel.pack()
ClickingGameButton.pack()
Everytime I run this I get a error saying _tkinter.TclError: image "pyimage1 doesn't exist". But the first file runs fine if I run it alone. I am using python idle 3.8.2.
