function Added()
   if game.Players.NumPlayers < 6 then
      local numplay = game.Players.NumPlayers - 6
	  print(numplay)
	  for i,v in pairs(game.Players:GetChildren()) do
		 if v.PlayerGui  then-- this is where i need help with
		 local addit = gui:clone()
		 addit.Frame.TextLabel.Text = numplay.." needed to begin. Invite your friends"
	  end
   end
end

how would i see if it has the Gui in it already?

Thanks for the help
