How to disable script when a part is not touched?

My script:

local Player = game:GetService("Players")
local debounce = false

function Touched(hit)
	if debounce == false then
		local player = Player:GetPlayerFromCharacter(hit.Parent)
		player:FindFirstChild("StarterGui").Animations.AnimationList.Animationcontroller.Disabled = false
		debounce = true
	end
end

function TouchEnded(hit)
	if debounce == true then
		local player = Player:GetPlayerFromCharacter(hit.Parent)
		player:FindFirstChild("StarterGui").Animations.AnimationList.Animationcontroller.Disabled = true
		debounce = false
	end
end

script.Parent.Touched:Connect(Touched)
script.Parent.TouchEnded:Connect(TouchEnded)

It doesn't work for me any suggestions?
