How come I can't clone this object to workspace?

Hi, what I'm trying to do here is spawn an object named "Foil" to workspace. The "Foil" is in a "Model" named Loot. The script is trying to identify if there is a object named "Foil" in workspace and if there is, then the script won't work. If there is no Foil in workspace, the "Foil" will spawn into the workspace, and move to a part's position.

Material = game.Lighting.Loot:getChildren()
Foil = game.workspace:findFirstChild("Foil")

	function Spawning()
  for i = 1, #Material do
  if Material[i] and Material[i]:findFirstChild("Foil") then
	if Foil.Parent ~= game.workspace then
	local Materials = Material[i]["Foil"]:Clone()
   Materials.Parent = workspace
	local Part = game.Workspace.Part
	if Part ~= nil then
	Materials:MoveTo(Part.Position)
	end
	elseif Foil.Parent == workspace then
	local p = nil
		return p
						end
					end
				end
    	    end
	while true do 
		wait(1)
		print("Spawning")
		Spawning()
	end
