Why wont my billboard gui frame show up above my characters head?

I made a billboardgui with a frame in it, the parent is the players head so it will show the players level above them, I know for a fact its not because it is inside my player and hidden because i tested that, I moved it around, it still didnt show, the background transparency is 0, and the visible bool value is set to true. Here is the code i made to create it so far if that helps at all.

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(char)
		local gui = Instance.new("BillboardGui", char.Head)
		local level = player.leaderstats.Level
		local frame = Instance.new("TextLabel", gui)
		frame.Size = UDim2.new(1,0,1,0)
		frame.Position = UDim2.new(0,0,0,0)
	end)
end)
