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)
