[Tkinter] Can't update label in new tk window, object has no attribute

[tompranks]

Hi, I have this code but i get the error "object has no attribute".

from tkinter import *

root = Tk()

root.geometry("300x300")

count = 20

pop_label = None

def ACdriver(option):
#	pop.destroy()
	global count
	if option == "UP":
		count = count + 1
	else:
		count = count - 1
	my_label.config(text=count)
	pop_label.config(text=count)

def ACwindowdriver():
	global pop
	pop = Toplevel(root)
	pop.title("My Popup")
	pop.geometry("150x200+00+00")
	pop.overrideredirect(True) #Borderless
	pop.config(bg="black")


	pop_label = Label(pop, bg="green", fg="white", font=("helvetica", 12))
	pop_label.config(text=count)
	pop_label.grid(row=1, column=0, pady=10)


	my_frame = Frame(pop, bg="black")
	my_frame.grid(row=1, column=1, pady=10)

	heatdriver = Button(my_frame, command=lambda: ACdriver("UP"), bg="black")
	heatdriver.grid(row=2, column=2, pady=10)

	colddriver = Button(my_frame, command=lambda: ACdriver("DOWN"), bg="black")
	colddriver.grid(row=3, column=2, pady=10)

def destroy():
	pop.destroy()


destroy_button = Button(root, text="destroy", command=destroy)
destroy_button.place(x=1, y=1)

ACdriver_button = Button(root, text="ACwindowdriver", command=ACwindowdriver)
ACdriver_button.pack(pady=50)

my_label = Label(root, text="")
my_label.pack(pady=20)



root.mainloop()

I am trying to update the number inside the new tk window called "pop" but the number only updates after i press "destroy" and "ACwindowdriver" again. When i press one button inside the window pop i get the error "'NoneType' object has no attribute 'config'".

Thankfull for all help.

Kind regards
Tom
