Can I have some help with this map choosing?

Ok, so I have a script in Workspace that jhas this text:

	h=Instance.new("Hint")
	h.Parent=game.Workspace
while wait(1) do
	h=Instance.new("Hint")
	h.Parent=game.Workspace
	
	script.StarterMusic:Play()
--variables	
	h.Text=""
	--round starts
	if game.Players.NumPlayers<=0 then
		while game.Players.NumPlayers<=0 do
			wait(1)
	h.Text="Waiting for 2 players..."
	
		end
		
	else
			i=5

			while wait(1) and i>0 do
		h.Text=i.." seconds until the round starts!"
		i=i-1
			end
			h.Text="Choosing a random map..."
local maps = game.ServerStorage["Maps"]:GetChildren()
			
			wait(3)
		 map = maps[math.random(1, #maps)]
		h.Text=map
		wait(1)
	end
end

What happens is the script freezes after it chooses the map. The only error I ever get is 06:09:49.080 - String expected. I think it's the way I' choosing the map. If so, how do I fix it? If not, what is it? Please help. Thanx.

It says string expected, because of line 30. You made the mistake of trying to display a message, of the physical model! Instead, put h.Text = map.Name , which is the string that it's asking for!
