Object Parser Error?

function objectParser(str)
	local obj = game.Players.LocalPlayer.PlayerGui
	local s, e = str:find'.-%.'
	if not s then
		return game[str:match'.+']
	else
		local object = str:match'.-%.'
		obj = game[object:sub(1, #object - 1)]
		print(object, str, e)
		str = str:sub(e)
		print(str)
		local leftovers = str
		for word in str:gmatch'%..-%.' do
			local s, e = str:find(word)
			leftovers = str:sub(e + 1)
			print(word)
			obj = obj[word:sub(2, #word-1)] -- Line 17
			print(leftovers)
		end
		return obj[leftovers]
	end

Lane is a StringValue and I'm using an ObjectParser to make it functional. I'm doing this so that the script can figure out which note is prioritized in a Dance Dance Revolution GUI game. Lane's value is a full name of an object. For example Lane.Value=Players.Player.PlayerGui.Game.Board.Lanes.LeftLane.16

Don't Know what's wrong. Please help.
