Nil value Argument 1?

    for i = 0, #teleplayers do
        randomspawn = math.random(1, #spawn_locations)
        game.Players:FindFirstChild(teleplayers[i]).Character.Torso.CFrame = CFrame.new(spawn_locations[randomspawn])
                wait()
                table.remove(teleplayers, i)
                wait()
                end

For an unknown reason I get the error "argument 1 nil value", so it's like not working out that the teleplayers is a value, which is starting to grind my teeth.
