Dancing emote tool makes error in console when emote not played on unequip?

Hi, this script works fine, but here's a problem when i equip it, then unequip it, it shows a error in the console

script below: enabled = false

local Tool = script.Parent;

local player = game.Players.LocalPlayer

function onActivated()

--This will check if it is enabled and then either start dancing or stop dancing

if enabled == false then

local humanoid = Tool.Parent:FindFirstChild("Humanoid")

local torso = Tool.Parent:FindFirstChild("Torso")

dancer = humanoid:LoadAnimation(Tool.dance)

Tool.DanceObject.Value = dancer

dancer:Play()

Tool.dancepart.Position = player.Character.Head.Position

Tool.dancepart.SongLoop:Play()

enabled = true

speed = player.Character.Humanoid.WalkSpeed

player.Character.Humanoid.WalkSpeed = 0

player.Character.Humanoid.JumpPower = 0

repeat

wait(1)

Tool.dancepart.Position = player.Character.Head.Position

until enabled == false

else

dancer:Stop()

dancer:remove()

Tool.dancepart.SongLoop:Stop()

enabled = false

player.Character.Humanoid.WalkSpeed = speed

player.Character.Humanoid.JumpPower = 50

end

end

function onUnequipped()

it happens here somewhere

player.Character.Humanoid.JumpPower = 50

dancer:Stop()

dancer:remove()

Tool.dancepart.SongLoop:Stop()

enabled = false

player.Character.Humanoid.WalkSpeed = speed

end

Tool.Activated:connect(onActivated)

Tool.Unequipped:connect(onUnequipped)
