How would i fix my map randomiser with a number error?

I have been trying to make a map randomiser for the past 2 hours and i am having trouble it says "attempt to index number with 'Map'" on line 3 i have tried math.random(1, #Maps), random.new(1, #Maps) and neither have worked please help as i cant continue making a game without this working.

EDIT: I changed the code a little still dosent work NEW ERROR: ServerScriptService.MapChooser.Selector:14: attempt to index number with 'Sky'

local Maps = game.ServerStorage:WaitForChild("Maps"):GetChildren()
local Map = math.random(1, #Maps)
local MapClone = Maps[Map]:Clone()
local Intermission = game.ReplicatedStorage:WaitForChild("MapStuff"):WaitForChild("Intermission")

while wait() do
	print("Intermission.")
	if Intermission.Value == true then
		wait()
	elseif Intermission.Value == false then
		print("No Longer Intermission.")
		MapClone.Map.Parent = workspace
		print("Cloned To Workspace.")
		Map.Sky.Parent = game.Lighting
		print("Lighting.")
	end
end

I believe you need to add a bracket around it.

map = Maps[math.random(1, #Maps)]

The Map.Sky.Parent = game.Lighting is probably wrong. Maybe you should change it to Map.Sky.Parent = game:GetService("Lighting") .
