Why wont this script I duplicated work when it worked before?

I made a script that opened and closed a gui every time you clicked a button, it worked. I needed the same script for a different button, so I duplicated the script and put it in a different button and made a few changes to make a different gui appear. For some reason however, the copy of the script wont work, and it gives me an error that says:

CreateTerritoryGui is not a valid member of PlayerGui "Players.Paczki_TCBC.PlayerGui"

(CreateTerritoryGui is the gui I'm trying to make appear, and Paczki_TCBC is my username.)

here is the script that did work:

local Or = 1
local button = script.Parent
local editor = button.Parent.Parent.Editor
editor.Enabled = false

button.MouseButton1Up:Connect(function()
	Or = Or * -1
	if Or == -1 then
		editor.Enabled = true
	elseif Or == 1 then
		editor.Enabled = false
	
	end
end)

and here is the one that did not work:

local choice = 1
local button = script.Parent
local editor = button.Parent.Parent.CreateTerritoryGui
editor.Enabled = false

button.MouseButton1Up:Connect(function()
	choice = choice * -1
	if choice == -1 then
		editor.Enabled = true
	elseif choice == 1 then
		editor.Enabled = false
	
	end
end)

i think there is a book gear is able to help get this plugin : https://www.roblox.com/library/997404854/Catalog-Loader? and type 1001541309 in the blue box there is a ui is like a page turns the frame named 1 to framed named two

Make sure there is a thing called CreateTerritoryGui (script.Parent.Parent.Parent.CreateTerritoryGui)
