Server script (in serverscriptservice):


local lobby_Duration = 10
local round_Duration = 10
local maps = game:GetService('ReplicatedStorage'):WaitForChild('Map'):GetChildren()
local timerval = game.ReplicatedStorage:WaitForChild("TimerValue")

local function RTimer ()
    while wait() do
        for l = lobby_Duration, 0, -1 do
            timerval.Value = 'Intermission: '..l
            wait(1)

            if l == 0 then
                local map = maps[math.random(#maps, 1)] -- change to your map name
                timerval.Value = 'Teleporting players to '..map.Name
                wait(1)
                map.Parent = workspace

                local players = game.Players:GetChildren()

                for i = 1, #players do
                    players[i].Character:MoveTo(Vector3.new(-122.5, 55.5, -41.5))
                end

                wait(1)

                for g = round_Duration,0, -1 do
                    timerval.Value = 'Round '..g..' seconds left'
                    wait(1)

                    if g == 0 then
                        timerval.Value = 'Round over'
                        wait(2)
                        timerval.Value = 'Teleporting players to lobby'
                        wait(1)
                        for i = 1, #players do
                            players[i].Character:MoveTo(Vector3.new(-122.5, 55.5, 2.5))
                        end

                        map.Parent = maps
                        wait(1)
                        -- repeat again
                    end
                end
            end
        end
    end
end

spawn(RTimer)

The reason for this is on the line where you choose a random map, math.random should have a min argument that is lesser than the max argument, you are doing the opposite, that's why it's not choosing a map and returning nil, the fix would probably be to swap the two values

if l == 0 then
    local map = maps[math.random(1, #maps)] -- this is the problem
    nametimerval.Value = 'Teleporting players to '..map.Name
    -- Your code

Then it returns an error invalid argument #2 to 'random' (interval is empty) Br0kenM1ndss 7 — 2y

Could it be line 3 where you havent defined what map is? im talking about ' local maps = ' iRedStoneCraftYT 0 — 2y

@Br0kenM1ndss that means that your maps folder has 0 children (maps) inside it AnasBahauddin1978 715 — 2y
