I am entirely confused of why this works on one game but not this one?

I honestly don't know why this isn't working, it works on my other game, exact same scripting, exact locations of all models and names, I just don't understand. Please someone help.

Error: Workspace.Part3.Script:10: attempt to index local 'Player' (a nil value)

local Players = game:GetService('Players')
local debounce = false
local Teleport = "Part4" 
function onTouched(hit)
	if debounce == false then
		debounce = true
	local OnTouchSky = game.ServerStorage.SkyChanger2
	local OnTouchSkyCopy = OnTouchSky:Clone()
	local Player = Players:FindFirstChild(hit.Parent.Name)
	   	if Player.PlayerGui:FindFirstChild("SkyChanger") then
			if script.Parent.Locked == false and script.Parent.Parent:findFirstChild(Teleport).Locked == false then script.Parent.Locked = true script.Parent.Parent:findFirstChild(Teleport).Locked = true
				local Pos = script.Parent.Parent:findFirstChild(Teleport)
				hit.Parent:moveTo(Pos.Position) wait(1) script.Parent.Locked = false script.Parent.Parent:findFirstChild(Teleport).Locked = false
			end
	        Player.PlayerGui.SkyChanger:Destroy()
		    OnTouchSkyCopy.Parent = Player.PlayerGui
			debounce = false
	else
		if script.Parent.Locked == false and script.Parent.Parent:findFirstChild(Teleport).Locked == false then script.Parent.Locked = true script.Parent.Parent:findFirstChild(Teleport).Locked = true
				local Pos = script.Parent.Parent:findFirstChild(Teleport)
				hit.Parent:moveTo(Pos.Position) wait(1) script.Parent.Locked = false script.Parent.Parent:findFirstChild(Teleport).Locked = false
			end
			OnTouchSkyCopy.Parent = Player.PlayerGui
			debounce = false
	    end
	end
end
script.Parent.Touched:Connect(onTouched)

it also could be not working bc one game has filtering enabled off and this one has it on. if not then do what royaltoe says
