Really really need help. The script won't work with more than two people?

no errors, only teleports one player

local hint = Instance.new("Hint")

local maps = ss:GetChildren()
local tim = 160

wait(1)

    maps:Destroy()
end
end
    randommap = maps[math.random(1, #maps)]
    hint.Parent = Workspace

hint.Text = "Starting in 20 seconds!"
wait(15)
for i = 5,1, -1 do
    hint.Text = i
    wait(1)
end
