	ls.Parent = plr
	
	local stage = Instance.new("StringValue")

	char.Humanoid.Touched:Connect(function(touch)
				
		if touch.Parent == checkpoints then
			if (tonumber(touch.Name) and tonumber(touch.Name) > tonumber(stage.Value)) or touch.Name == "End" then

		humanoid.Touched:Connect(function(touch)
				
			if touch.Parent == checkpoints then
				if (tonumber(touch.Name) and tonumber(touch.Name) > tonumber(stage.Value)) or touch.Name == "End" then
