Hello.

Solution:

You forgot the "=" while making a variable.

Fixed Script:

local tool = script.Parent

local anim = Instance.new("Animation")
anim.AnimationId = "rbxassetid://4928303202"

local track
tool.Activated:Connect(function()
    track = script.Parent.Parent.Humanoid:LoadAnimation(anim)
    track.Priority = Enum.AnimationPriority.Action
    track.Looped = false
    track:Play()
end)
tool.Unequipped:Connect(function()
    if track then
        track:Stop()
    end
end)
