An object reference is required to access non-static member (CS0120)

 using UnityEngine;
 using UnityEngine.Networking;
 
 public class Player_NetworkSetup : NetworkBehaviour {
 
     [SerializeField] Camera FPSCharacterCam;
     [SerializeField] AudioListener audioListener;
 
         //Use this for Init
     void start ()
     {
         if(isLocalPlayer)
         {
             GameObject.Find("Scene Camera").SetActive(false);
             GetComponent<CharacterController>().enabled = true;
             GetComponent<UnityStandardAssets.Characters.FirstPerson.FirstPersonController>().enabled = true;
             FPSCharacterCam.enabled = true;
             AudioListener.enabled = true;
         }
     }
 
  }
