why doesn't my animation load and play?

--choppy choppy >:3

local tool = script.Parent
local toolDeb = false

tool.Activated:connect(function(hit)
	if toolDeb == false then
		local chopAnim = Instance.new("Animation", game.Players.LocalPlayer.Character)
		chopAnim.AnimationId = "http://www.roblox.com/Asset?ID=1079330549"
		local chopAnimTrack = game.Players.LocalPlayer.Character.Humanoid:LoadAnimation(chopAnim)
		chopAnimTrack:Play()
		wait()
	end
end)

It doesn't play...

Most people usually do it like this :

local chopanim = Instance.new("Animation")
chopanim.AnimationId = "http://www.roblox.com/Asset?ID=1079330549"

To play :
local animTrack = Humanoid:LoadAnimation(chopanim)
animTrack:Play()
