Troubling animations always screw me.. ( Any help? )

I'm trying to make a tool that when you click it, It plays an animation and it gives a menu to the player that the person clicked. I've already created a script for giving the "GiveMenu" tool to the player. I get an error about the Animation failing to load when I get the tool in my Inventory, and when I click a player. Any help?

Note: I put all of this into a Local Script and the tool is located in Server Storage.

Errors:

"Animation "http://www.roblox.com//asset/?id=44911345&serverplaceid=1372052778" failed to load in "Animation.AnimationId": Animation failed to load"

"Players.LennonLight.Backpack.GiveMenu.Animation:11: attempt to index local 'whatWasClicked' (a nil value) (Line 11)"

local animation = Instance.new("Animation")
wait(1)
local plr = game.Players.LocalPlayer
local Mouse = plr:GetMouse()
local player = plr.Character

animation.AnimationId = "rbxassetid://44911345"
animTrack = player.Humanoid:LoadAnimation(animation)

Mouse.Button1Down:connect(function(whatWasClicked)
	if whatWasClicked.Parent.Name == "Torso" then
		animTrack:Play()
		wait(0.75)
		player:FindFirstChild("Backpack").GiveMenu:Destroy()
		game.ServerStorage.GiveMenu:Clone().Parent = whatWasClicked:FindFirstChild("Backpack")
		if whatWasClicked.Backpack == nil then
			game.ServerStorage.GiveMenu:Clone().Parent = whatWasClicked.Character:FindFirstChild("Backpack")
		end
	end
end)

You may want to use the animation from alvin blox. Go to his yt channel and look up animation. And then watch his video. It should solve any problem with animation.
