Weld script doesn't work in Workspace? [Not Answered!]

So I try and clone this Camera into game.Workspace, And when ever I test this in Solo Mode via Studio it works perfectly but in Server's it wont work. I've tried some prints for debugging and it seems that the Weld Script won't work in the Workspace. Any help?

local Previous = nil

function Weld(Objects)
    for i,v in pairs(Objects:GetChildren()) do
        if v:IsA("Part") or v:IsA("UnionOperation") then
            if Previous ~= nil then
                local Weld = Instance.new("Weld", Previous)
                Weld.Part0 = Previous
                Weld.Part1 = v
                Weld.C0 = Previous.CFrame:inverse() 
                Weld.C1 = v.CFrame:inverse()
            end
            Previous = v
        end
    end
    for i,v in pairs(Objects:GetChildren()) do
        if v:IsA("Part") or v:IsA("UnionOperation") then
            v.Anchored = false
        end
    end
    script:Destroy()
end

Weld(script.Parent)

The Script that clones the hole model into game.Workspace, Well not into game.Workspace it clones the model into a Player's current camera.

wait(1)
local Player = game.Players.LocalPlayer
repeat wait() until game.Workspace:FindFirstChild(Player.Name)
local Character = Player.Character
local Camera = game.Workspace.CurrentCamera

Camera:ClearAllChildren()

--Player.CameraMode = "LockFirstPerson"

local NewModel = Instance.new("Model", Camera)
local Humanoid = Instance.new("Humanoid", NewModel)
local Arm = Character["Right Arm"]:Clone()
Arm.Parent = NewModel
local BodyColors = Instance.new("BodyColors", NewModel)
BodyColors.RightArmColor = BrickColor.new("Pastel brown")
Arm.CanCollide = true
local ModelCamera = game.Lighting.Camera:Clone()
ModelCamera.Parent = NewModel

function WeldCamera()
    local Weld = ModelCamera.Handle:FindFirstChild("ArmWeld")
    if not Weld then
        Weld = Instance.new("Weld", ModelCamera.Handle)
        Weld.Name = "ArmWeld"
        Weld.Part0 = ModelCamera.Handle
        Weld.Part1 = Arm
    end
    Weld.C0 = CFrame.new(0.8, 0.8, 0) * CFrame.Angles(0, math.pi/2, 0)
end

function WeldArm()
    local Weld = Arm:FindFirstChild("Weld")
    if not Weld then
        Weld = Instance.new("Weld", Arm)
        Weld.Part0 = Character.Head
        Weld.Part1 = Arm
    end
    Weld.C0 = Character.Head.CFrame:toObjectSpace(Camera.CoordinateFrame) * CFrame.new(0.9, -1, -1.5) * CFrame.Angles(math.pi/2, 0, 0)
end

while wait() do
    coroutine.resume(coroutine.create(function()
        WeldArm()
    end))
    coroutine.resume(coroutine.create(function()
        WeldCamera()
    end))
end
