How do i fix this voice command?

local Admin = {""}
local Owner = {""}
local Banned = {""}
local BuyAdmin = {""}

local mapName = {"Spaceship","Floatings",""} -- here put your mapnames for command map [Mapname]

function onChat(msg, recipient, speaker)

local source = speaker.Name

if source == Admin or source == Owner or source == BuyAdmin and
	 string.sub(msg,1,10) == "choose map " and
	 string.sub(msg,6) == mapName
	then
game.Lightning.mapName:clone()


	end	
end

	if source == Admin or source == Owner or source == BuyAdmin and
	 string.sub(msg,1,10) == "remove map " then
	if string.sub(msg,6) == mapName
	then
game.Lightning.mapName:remove()

	end
	
	
	end

its not working its supposed to do choose map check if map in mapName list and put the map in workspace if it exists.
