Permission = {"andrewboy159","PLAYER","PLAYER"} -- Players who can run the map.
RunText = "/computer run obby2" -- Text the Players have to say to run the map.
StopText = "/computer stop obby2" -- Text the Players have to say to stop the map.
Map = "Obby2" -- The name of the map in ServerStorage.

game.Players.ChildAdded:connect(function(Player)
Player.Chatted:connect(function(Chat)
local function OnChatted()
for i = 1, #Permission do
if Player.Name == Permission[i] then
if string.lower(Chat) == RunText then
if not game.Workspace:FindFirstChild("Obby2") then
game.ServerStorage.Obby2:Clone().Parent = game.Workspace
elseif string.lower(Chat) == StopText then
if game.Workspace:FindFirstChild(Map) then
game.Workspace[Map]:Remove()
end

game.Players.PlayerAdded:connect(function(Player)
    Player.Chatted:connect(function(Chat) local onChatted(Chat, Player) end)
end)

Tab your code. It's hard to know what exactly it's doing if you don't.
