I Asked How To Make If An Update Happens Something Happens (https://scriptinghelpers.org/questions/94364/how-to-make-an-update-system#) It (Did) Work (Just Stopped) But Im Wondering How I Would Clone A Gui Into All Players As It Dont Work!

local UpdateGui = game.ServerStorage.Update
local Update = UpdateGui:Clone()

game.Players.PlayerAdded:Connect(function(Player)
	while wait() do
		if game:GetService("MarketplaceService"):GetProductInfo(game.PlaceVersion).Updated == true then
			Update.Parent = Player.PlayerGui
		end
	end
end)
