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.
