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)
