Idle animation for my tool is overriding my attack animation, help?

(Read to bottom)

When I equip my hammer tool, it plays an idle animation because of the following Local Script:

local tool = script.Parent
local Anim = Instance.new("Animation")
Anim.AnimationId = "rbxassetid://6636798666"
local track
tool.Equipped:Connect(function()
    track = script.Parent.Parent.Humanoid:LoadAnimation(Anim)
    track.Priority = Enum.AnimationPriority.Action
    track.Looped = true
    track:Play()
end)

tool.Unequipped:Connect(function()
    if track then
        track:Stop()
    end
end)

I added another normal Script into the tool, so that when you click, the attack animation plays:

local Tool = script.Parent
local Animation = Tool.Animation

Tool.Activated:Connect(function()
    local Character = Tool.Parent
    local Humanoid = Character.Humanoid 
    wait(3)
    local AnimationTrack = Humanoid:LoadAnimation(Animation)
    AnimationTrack:Play()
end)

I'm having a slight problem though, when I click for the attack animation to play, the arms that are supposed to move when the attack animation plays don't move. Its almost like the arm's movements are being voided because of the idle animation.

I want to know if there is anything I can add to the ATTACK ANIMATION script (second script shown) that will temporarily disable the IDLE ANIMATION (first script shown) Local Script so the attack animation can play, and then when it is finished, the idle animation will begin playing again, and the idle animation's local script will start running.

How can I do this?
