My random map script isnt working and I dont know why???

MY script is

playarea = math.randomseed(1,3)
min = 0
sec = 5

while true do
	wait(0.1)
	if script.Parent.Parent.GameMode.Loaded.Value == true then
			script.Parent.Text = (min..":"..sec)
			wait(1)
			sec = sec - 1
			if sec == 0 then
				min = min - 1
				sec = 59
			end
	end
	end

while true do
	wait(0.1)
	if min == 0 and sec == 0 then
		game.Workspace("Map" ..playarea):Destroy()
		playarea = math.randomseed(1,3)
		wait(60)
		game.Lighting("Map" ..playarea):Clone().Parent = game.Workspace
	end
end
	

I dont know why its not working also roblox forums shutdown forever :(

math.randomseed() isn't the same as math.random(). Randomseed sets the seed that Random uses. Therefore, you just change the script to:

local playarea = math.random(1,3)
local min = 0
local sec = 5

while true do
    wait(0.1)
    if script.Parent.Parent.GameMode.Loaded.Value == true then
            script.Parent.Text = (min..":"..sec)
            wait(1)
            sec = sec - 1
            if sec == 0 then
                min = min - 1
                sec = 59
            end
    end
    if min == 0 and sec == 0 then
        game.Workspace("Map" ..playarea):Destroy()
        playarea = math.random(1,3)
        wait(60)
        game.Lighting("Map" ..playarea):Clone().Parent = game.Workspace
    end
end

I did as some comments suggested, too.

One thing, however. I suggest you use game.ServerStorage over game.Lighting. ServerStorage is actually made for what you are using.

Thanks,
