Sync Var not syncing on client.

For whatever reason, the integer multiscene is successfully being set on the server, but client side it doesn't change when connecting to a server. Here is the script:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.Networking;
 using System.Collections.Generic;
 using UnityEngine.SceneManagement;
 using UnityEngine.Networking.Types;
 public class NManage: NetworkBehaviour {
 
     [SerializeField]
     GameObject[] spawners;
     public List<GameObject> allPlayers = new List<GameObject>();
 
 
 
     public GameObject localPlayer;
 
     public networkSetup NS;
 
     public NetworkManager NM;
 
     public variableKeeper VK;
 
     public int maxPlayers = 10;
 
     [SyncVar(hook="setScene")]
     public int multiScene = 0;
 
     // Use this for initialization
     void Start () {
         VK = gameObject.GetComponentInParent<variableKeeper> ();
 
         NM = gameObject.GetComponentInParent<NetworkManager> ();
     }
     
     // Update is called once per frame
     void Update () {
 
 
     setScene(SceneManager.GetSceneByName (VK.loadSC).buildIndex);
 
         if (localPlayer == null) {
             localPlayer = GameObject.FindGameObjectWithTag ("localPlayer");
 
         } else if (NS == null) {
             NS = localPlayer.GetComponent<networkSetup> ();
         } else if (NS.isServer) {
             if (spawners.Length <= 0) {
                 spawners = GameObject.FindGameObjectsWithTag ("Spawner");
             } else if (spawners [0].activeSelf != true) {
                 for (int i = 0; i < spawners.Length; i++) {
                     spawners [i].SetActive (true);            
                 }
             }
             
 
             if (localPlayer != null && !allPlayers.Contains (localPlayer)) {
                 allPlayers.Add (localPlayer);
             } 
 
             if (allPlayers.Count < GameObject.FindGameObjectsWithTag ("remotePlayer").Length + 1) {
                 for (int x = 0; x < GameObject.FindGameObjectsWithTag ("remotePlayer").Length; x++) {
                     if (!allPlayers.Contains (GameObject.FindGameObjectsWithTag ("remotePlayer") [x])) {
                         allPlayers.Add (GameObject.FindGameObjectsWithTag ("remotePlayer") [x]);
                     }
                 }
             } else if (allPlayers.Count > GameObject.FindGameObjectsWithTag ("remotePlayer").Length + 1) {
                 for (int x = 0; x < allPlayers.Count; x++) {
                     if (allPlayers [x] == null) {
                         allPlayers.RemoveAt (x);
                     }
                 }
             }
         }
 
         NM.maxConnections = 10;
 
 
     }
         
 
     public void joinGame(string ip, int port){
         NM.networkAddress = ip;
         NM.networkPort = port;
         NM.StartClient ();
         //SceneManager.LoadScene (SceneManager.GetSceneAt(multiScene).name, LoadSceneMode.Additive);
     }
 
     public void setScene(int sceneNum) {
         if(multiScene != sceneNum && isServer) {
             multiScene = sceneNum;
         }
     }
