hello, please, anyone would be able to help me with a mistake Assets/skrypty/MenagerPolonczen.cs(11,4): error CS1525: Unexpected symbol `void'

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

///
/// Skrypt odpowiadający za łączenie się z serwerem (oraz rozłączanie i utrate połączenia)
///
public class MenagerPolonczen : Photon.MonoBehaviour {
}

void Start () {
	
}


void Update () {
	
}

public void Polacz() {
    PhotonNetwork.ConnectUsingSettings("0.1");
}

void OnGUI() {
    GUI.Label(new Rect(0, 0, 200, 20), PhotonNetwork.connectionStateDetailed.ToString());
}

void OnjoinedLobby() {
    Debug.Log("jojneliśmy lobby")
}

}

I think your problem is the closing bracket (}) after MonoBehaviour

public class MenagerPolonczen : Photon.MonoBehaviour { }

Try changing this line to:

public class MenagerPolonczen : Photon.MonoBehaviour {
