[Answered]Why wont my GUI appear visible even when visible is turned on in properties?

My script that I have created makes a GUI visible when I press the key "R". However when I run the script and press R the GUI says that it is visible in the properties, however I still cannot see the GUI. I think the problem lies inside the settings of the GUI but I haven't found any errors.

Side note: The script is local and is stored in the Starterpack.

Here is a picture of my GUI that I want to open: https://gyazo.com/bda261e322fcf93ed675369de887bc80

Here is my code:

repStorage = game:GetService("ReplicatedStorage")
BuildRoad = repStorage:WaitForChild("BuildRoad")
BuildStructure = repStorage:WaitForChild("BuildStructure")

while game.Players.LocalPlayer == nil do
	wait()
end

plr = game.Players.LocalPlayer
mouse = plr:GetMouse()
local RoadBuilding = script.Parent.Parent.StarterGui.ScreenGui.RoadBuilding
mouse.KeyDown:Connect(function(key)
	if key == "r" then
		print("pressing r")
		if game.StarterGui.ScreenGui.RoadBuilding.Visible == false then
			print("closed to open")
			game.StarterGui.ScreenGui.RoadBuilding.Visible = true
		else
			print("open to closed")
			game.StarterGui.ScreenGui.RoadBuilding.Visible = false
		end
	end
end)

There are too many wrongs in your code. First of all, mouse.KeyDown is deprecated. Do not use it for new work. Use UserInputService

Second, your GUI's location isn't StarterGui. If you make StarterGui's GUI visible it won't turn visible on of your script. You should use Player.PlayerGui.ScreenGui.RoadBuilding.Visible = true

Third, this is not a wrong in your script but you can reach Player by using local Player = game.Players.LocalPlayer but for that your script MUST be LocalScript.

Fourth, and yeah as I said at Third, use LocalScript. That's what you should use in GUIs.

I suggest you to re-type your script from the start. It's not long and re-typing it would be healthier for you.
