For some reason. My MouseButton1Click script won't even run? Help!

I'm trying to make a localscript that when the button is pressed. the switch moves to the other side. But i havent even made it to that point! The "Script.Parent.MouseButton1Click:Connect(function()" Isnt working. Its not even firing. I assume one of the variables is making it wait for eternity or something. Or roblox is lagging. But what am I doing wrong?

-- Services
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

-- Script Values
local Mode = "WonderLand"
local CoolDown = false

--Objects
local BackGround = script.Parent.Parent
local Button = script.Parent

local Player = Players.LocalPlayer

local WonderButton = BackGround.WonderLand
local HorridButton = BackGround.HorridLand


--Script

script.Parent.MouseButton1Click:Connect(function() --Not Working
	print("Switch Pressed")
	if not CoolDown and Mode == "WonderLand" then
		CoolDown = true
		Mode = "HorridLand"
		ReplicatedStorage:FindFirstChild("HorridLand").Parent = game.Workspace
		game.Workspace:FindFirstChild("WonderLand").Parent = ReplicatedStorage
		Button:TweenPosition(HorridButton.Position)
		CoolDown = false
	elseif not CoolDown and Mode == "HorridLand" then
		CoolDown = true
		Mode = "WonderLand"
		ReplicatedStorage:FindFirstChild("WonderLand").Parent = game.Workspace
		game.Workspace:FindFirstChild("HorridLand").Parent = ReplicatedStorage
		Button:TweenPosition(WonderButton.Position)
		CoolDown = false
	end
end)

I highly suggest using

WaitForChild("Ins")

Your object could happen to not load in time, therefore bugs out or something similar.

I fixed it!

-- Services
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local Lighting = game:GetService("Lighting")

-- Script Values
local Mode = "WonderLand"
local CoolDown = false

--Objects
local BackGround = script.Parent.Parent
local Button = script.Parent

local Player = Players.LocalPlayer
local Safe = Player:FindFirstChild("Safe")

local WonderButton = BackGround.WonderLand
local HorridButton = BackGround.HorridLand


--Script

script.Parent.MouseButton1Click:Connect(function()
	print("Switch Pressed")
	if CoolDown == false and Mode == "WonderLand" then --MAKES IT DARKER AND GOTH
		CoolDown = true
		Mode = "HorridLand"
		Button:TweenPosition(HorridButton.Position, nil, nil, 0.7)
		wait(0.7)
		ReplicatedStorage:FindFirstChild("HorridLand").Parent = game.Workspace
		game.Workspace:FindFirstChild("WonderLand").Parent = ReplicatedStorage
		Lighting.ClockTime = 1
		wait(0.4)
		CoolDown = false
	elseif CoolDown == false and Mode == "HorridLand" then -- MAKES IT LESS GOTH
		CoolDown = true
		Mode = "WonderLand"
		Button:TweenPosition(WonderButton.Position, nil, nil, 3.4)
		wait(3.4)
		ReplicatedStorage:FindFirstChild("WonderLand").Parent = game.Workspace
		game.Workspace:FindFirstChild("HorridLand").Parent = ReplicatedStorage
		Lighting.ClockTime = 14
		wait(0.6)
		CoolDown = false
	end
end)

Heh.. My error was i was trying to use TweenService for a gui...
