Why won't this script work?

I'm trying to make a force choke script but nothing happens. No errors show in output either.

-- Created by Avectus
wait(5)
-- Variables
local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()

local walkspeed = Player.Character["Humanoid"].WalkSpeed

local choking = script.choking

local choker = script.chokerAnim
local chokerAnim = Player.Character["Humanoid"]:LoadAnimation(choker)

local chokeable = script.chokeable

Mouse.KeyDown:connect(function(key)
	if key == "r" then
	if chokeable == true then
		chokeable = false
	local enemy = Mouse.Target.Parent:FindFirstChild("Humanoid")
	if enemy ~= nil then
		local chokingAnim = Mouse.Target.Parent:FindFirstChild("Humanoid"):LoadAnimation(choking)
		wait()
		chokingAnim:Play()
		chokerAnim:Play()
		
		walkspeed = 0
		enemy.WalkSpeed = 0
		
		for i = 0, 10 do
		enemy.Parent.Torso.CFrame = enemy.Parent.Torso.CFrame + Vector3.new(0, 0.3, 0)
		wait(0.1)
		end
		enemy.Parent["Torso"].Anchored = true
		
		for i = 0, 10 do
			enemy.Health = enemy.Health - 5
			wait(0.2)
		end
		
		
		chokeable = true
		chokingAnim:Stop()
		chokerAnim:Stop()
		
		walkspeed = 16
		enemy.WalkSpeed = 16
		
		enemy.Parent["Torso"].Anchored = false
	end
	end
	end
end)

Could someone please tell me why?

Thanks.
