This script doesn't work, and the animation won't play/stop? Any helo?

local human = game.Players.LocalPlayer.Character.Humanoid
local hold = human:LoadAnimation(script.Parent.hold)
local tool = script.Parent
tool.Equipped:connect(function()
hold:Play()
end)
tool.Unequipped:connect(function()
hold:Stop()
end)

This is all located in a localscript. When I Play solo, the animation does not play (reposted question because it wasn't answered)
