How to synchronize Photon networked values with text in the GUI

I have my players health synchronizing over photonview, I want these values to go to a Canvas > image > text, but whenever I use standard drag and drop using the prefabs, the referenced script for the health returns null. //Health bar script for player 2 using UnityEngine; using System.Collections; using UnityEngine.UI;

     public class HealthBar2 : Photon.MonoBehaviour
     {
         public HealthPlayer2 health;
         public Text valueText;
         public float MaxValue { get; set; }
         public float value
         {
             set
             {
                 string[] tmp = valueText.text.Split(':');
                 valueText.text = tmp[0] + ":" + health.health2.ToString();
             }
         }
         // Use this for initialization
         void Start()
         {
             health = GetComponent<HealthPlayer2>();
         }
     
         // Update is called once per frame
         void Update()
         {
             if (health = null)
             {
                 health = GetComponent<HealthPlayer2>();
             }
             value = health.health2;
         }
     }
     
     
     
     
     
     //player 2's health script
     using UnityEngine;
     using System.Collections;
     
     public class HealthPlayer2 : Photon.MonoBehaviour {
         public float health2 = 1000f;
         // Use this for initialization
         void Start () {
     
         }
         public void TakeDamage(float amt)
         {
             health2 -= amt;
             if (health2 <= 0)
             {
                 Die();
             }
         }
         void Die()
         {
             PhotonNetwork.Destroy(gameObject);
         }
     }
