Why isn't this tool script running at all? Nothing works.

local plr= game:GetService("Players").LocalPlayer
local char = ((character and character.Parent ~= nil and character) or plr.CharacterAdded:wait())
if not char or not char.Parent then
    character = plr.CharacterAdded:Wait()
end

local hum= char:WaitForChild("Humanoid")
local tool= script.Parent


local Left=nil
local Right=nil
Left = hum:LoadAnimation(script:WaitForChild("Left"))
Right = hum:LoadAnimation(script:WaitForChild("Right"))

tool.Equipped:connect(function()
    print"equipped yes"
hum.Seated:connect(function(isSeated,seat)
    if isSeated then
    if  seat:FindFirstChild("Left") then
        print"oop"
        Left:Play()
    elseif seat:FindFirstChild("Right") then
        print"oop"
        Right:Play()
    end
        else
        Left:Stop()
        Right:Stop()
    end
end)


end)

I'm trying to make it so once you equip the tool then sit on a seat that has a object "Left", a left animation plays. But nothing seems to be working, any advices??
