How do I get this animation toplay when i use the tool?

Tool = script.Parent
local player = game.Players.LocalPlayer
repeat wait() until player.Character ~= nil
local hum = player.Character:WaitForChild("Humanoid")
local animation = script.Parent.ExportAnim --Change DanceAnim to the name of your animation.
local AnimTrack = hum:LoadAnimation(animation) --Loads the animation into the humanoid.
Tool.Activated:connect(function(mouse) --If you're using a tool, change Selected to Activated, and get rid of the code on the next line. Otherwise, keep this the same.
        AnimTrack:Play()
    end)
end)
Tool.Unequipped:connect(function() --If you're using a tool, change Deselected to Unequipped. Otherwise keep it the same.
    AnimTrack:Stop()
end)

I want to make a bomb so that when you use it it throws it with an animation, this is what I havebut its not working?
