Working, but not working?

The following code is supposed to generate a 'Ghost' (model) based on the camera's coordinate frame. The ghost model appears in the game, but it doesn't move at all from the original position it was in when I made it.

What happens is a new camera called LocalBin is created (a container for my local parts), the Ghost model is inserted into it, a part called weldBrick is created and placed at the camera's CoordinateFrame (for creating a weld between the camera and ghost), and a weld is created that is supposed to link the ghost and weldBrick.

The hierarchy is as follows:

Workspace>LocalBin>Ghost, weldBrick, Weld

No output errors.

repeat wait() until Workspace.CurrentCamera ~= nil

-- attempt to find a container; create a new one if it doesn't exist
local container = Workspace:FindFirstChild("LocalBin")
if not container then
    container = Instance.new("Camera")
    container.Name = "LocalBin"
    container.Parent = Workspace
end

-- 'container' will be used to contain all local parts. Below I copied the code from
-- before to create a local platform.

function update()
    camera = game.Workspace.CurrentCamera

    weldBrick = Instance.new("Part")
    weldBrick.CFrame = Workspace.CurrentCamera.CoordinateFrame
    weldBrick.Anchored = true
    weldBrick.CanCollide = false
    weldBrick.Transparency = 0.5
    weldBrick.Name = "weldBrick"

    ghost = script.Ghost
    ghostClone = ghost:clone()

    for i, v in pairs(container:GetChildren()) do
        if v.Name == "Ghost" or v.Name == "weldBrick" or v.Name == "Weld" then
            v:Destroy()
        end
    end

    ghostClone.Parent = container
    weldBrick.Parent = container

    weld = Instance.new("Weld", container)
    weld.Part0 = ghostClone.Middle
    weld.Part1 = weldBrick
    weld.C0 = CFrame.new(5, 0, 5)
end
