Module Script with global objects?

Dear ScriptingHelpers Community,

My script kind of works but I am not able to toggle my imablelabel visible state. Here is my code:

local popup = {} 
 
local windowGui = nil
local windowImage = nil

function popup.create()
	windowGui  = Instance.new("ScreenGui")
	windowGui.Parent = script.Parent

	windowImage = Instance.new("ImageLabel")
	windowImage.Parent = windowGui
	windowImage.Position = UDim2.new(0, 25, 0, 50)
	windowImage.Size = UDim2.new(0, 100, 0, 100)
	windowImage.Image = "rbxassetid://133293265"
end
 
function popup.toggle(state)
	windowImage.Visible = state
end
 
return popup

I can see my Image but if my script calls toggle it doesn't change the visible state. What is wrong?

Maybe because it's nil? Module scripts act as dictionaries and the variables not connected to the module table will not be saved after you run a function.

local popup = {} 

popup.windowGui = nil
popup.windowImage = nil

function popup.create(self)
    local windowGui  = Instance.new("ScreenGui")
    windowGui.Parent = script.Parent
    self.windowGui=windowGui

    local windowImage = Instance.new("ImageLabel")
    windowImage.Parent = windowGui
    windowImage.Position = UDim2.new(0, 25, 0, 50)
    windowImage.Size = UDim2.new(0, 100, 0, 100)
    windowImage.Image = "rbxassetid://133293265"
    self.windowImage=windowImage
end

function popup.toggle(self,state)
    self.windowImage.Visible = state
end

return popup

Then you call it as a module instead of a function.

local popup=require(popup)
popup:create()
popup:toggle(true)

popup.create(popup) is the same as popup:create()
