I can't create a room in multiplayer

Here’s the error:

JoinRoom failed. A roomname is required. If you don’t know one, how will you join

stupidest mistake I’ve ever seen

Here’s the code:

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 
using UnityEngine.UI; 
using Photon.Pun; 
using Photon.Realtime; 
public class MenuManeger : MonoBehaviourPunCallbacks 
    [SerializeField] InputField joinInput; 
    [SerializeField] InputField createInput; 
    public void CreateRoom() 
        RoomOptions roomOptions = new RoomOptions(); 
        roomOptions.MaxPlayers = 4; 
        PhotonNetwork.CreateRoom(createInput.text, roomOptions); 
    public void JoinRoom() 
    public override void OnJoinedRoom()
