Photon : Multiplayer car race game Camera Set

hello everyone..

i am using photon realtime multiplayer plugin. and i have check worker demo..

In that demo they have third person controller script and third person camera script. Both are attached to the player..

I have created script for controlling car.. and camera is also following car very well..

here is my camera script :

 using UnityEngine;
 using System.Collections;
 
 public class NewCamera : MonoBehaviour {
 
     #region Private Variables
     [SerializeField]
     private float distanceAway;
     [SerializeField]
     private float distanceUp;
     [SerializeField]
     private float smooth;
     [SerializeField]
     private Transform follow;
     private Vector3 targetPosition;
     private Vector3 velocity = Vector3.zero;
     public float smoothing = 10;
     #endregion
 
     #region Properties (public)
 
     #endregion
     float angleBetween = 0.0f;
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () 
     {
         if(Input.GetKeyDown(KeyCode.Escape))
         {
             Application.Quit();
         }
     //}
 
     //void LateUpdate()
     //{
 
         targetPosition = follow.position + follow.up * distanceUp -  follow.forward * distanceAway;
         float T = Time.deltaTime * 2; 
         Debug.DrawRay(follow.position,Vector3.up * distanceUp, Color.red);
         Debug.DrawRay(follow.position,1f * follow.forward * distanceAway, Color.blue);
         Debug.DrawLine(follow.position,targetPosition,Color.yellow);
 
         transform.position = Vector3.Slerp(transform.position,targetPosition,smooth * Time.deltaTime);
         transform.position = Vector3.SmoothDamp(transform.position,targetPosition,ref velocity,10);
 
         transform.LookAt(follow);
     }
 }

now wen i attach my this camera script and car controller script.. , but code is not working.. camera does not follow my car..
