Stand Game Error with Stand Summoning?

So, I'm making a Jojo game, and starting off with a classical stand, however, this code doesn't seem to be working and is showing an error, but I can't seem to find it.

The Code:

local rp = game:GetService("ReplicatedStorage") local summon = rp:WaitForChild("Summon")

local TweenService = game:GetService("TweenService") local Debris = game:GetService("Debris")

summon.OnServerEvent:Connect(function(Player,isActive) local Character = Player.Character local Humanoid = Character.Humanoid local Hurmp = Character.HumanoidRootPart

if isActive then
    local Stand = script:WaitForChild("Stand"):Clone()

    for _, part in pairs(Stand:GetChildren())do
        if part:IsA("BasePart") then
            part.Transparency = 1
        end
    end

    Stand.Parent = Character
    Stand.PrimaryPart.CFrame = Hurmp.CFrame

    local weld = Instance.new("ManualWeld")
    weld.Name = "Controller"
    weld.Part0 = Stand.PrimaryPart
    weld.Part1 = Hurmp
    weld.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
    weld.Parent = weld.Part0

    local AnimControl = Stand:FindFirstChild("AnimControl")
    local standHumrp = Stand:FindFirstChild("HumanoidRootPart")

    local Idle = AnimControl:LoadAnimation(script.Idle)
    Idle:Play()

    for _, part in pairs(Stand:GetChildren())do
        if part:IsA("BasePart") and part ~= standHumrp then
            local goal = {}
            goal. Transparency = 0
            local info = TweenInfo.new(.5)
            local tween = TweenService:Create(part,info,goal)
            tween:Play()
        end
    end

    local goal = {}
    goal.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
    goal.C1 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame) * CFrame.new(3,1,2)--change to your stand position
    local info = TweenInfo.new(.5)
    local tween = TweenService:Create(weld,info,goal)
    tween:Play()
else
    local Stand = Character:FindFirstChild("Stand")
    if Stand then

        local Controller = Stand.PrimaryPart:FindFirstChild("Controller")
        if Controller then

            local standHumrp = Stand:FindFirstChild("HumanoidRootPart")

            for _, part in pairs(Stand:GetChildren())do
                if part:IsA("BasePart") and part ~= standHumrp then
                    local goal = {}
                    goal. Transparency = 1
                    local info = TweenInfo.new(.5)
                    local tween = TweenService:Create(part,info,goal)
                    tween:Play()
                end
            end

            local goal = {}
            goal.C0 = Controller.Part0.CFrame:ToObjectSpace(Controller.Part1.CFrame)
            goal.C1 = Controller.Part0.CFrame:ToObjectSpace(Controller.Part1.CFrame) * CFrame.new(0,0,0)
            local info = TweenInfo.new(.5)
            local tween = TweenService:Create(Controller,info,goal)
            tween:Play()

            tween.Completed:Connect(function()
                Debris:AddItem(Stand,.05)
            end)

        end
    end

end
