Detacting Collision Over Photon Network

I Made A MultiPlayer FPS the movement works and its smooth but the bullet detaction doesnt work for some reason ...

here is the scripts i use

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Health : MonoBehaviour {
 
     public Transform Player;
     public PhotonView Charac;
     public float H;
     public float Hheal;
     public Text HText;
     public bool CanDie;
     public Movement MoveScript;
 
     public GameObject Gun1;
     public GameObject Gun2;
     public float GunNumber;
     public bool CanChange;
     
     void Start () {
         Gun1.SetActive (true);
         Gun2.SetActive (false);
         GunNumber = 1;
     }
     void Intilize (){
         Player = GetComponent<Transform> ();
         MoveScript = Player.GetComponent<Movement>();
     }
 
     void Update () {
 
           // Hit Detatciton
 
         Hgain = MoveScript.Hhit;
         if(Hgain == 1 ){
             H = H + 10;
         }
         Hlost = MoveScript.Hloss;
         Hlost = Hlost * 2;
         H = H - Hlost;
         // Respawn
         if (H <= 0  && CanDie == true){
             SpawnMyPlayer();
         }
 
         HText.text = "H " + Mathf.Round (H / 10) * 10;
  
 
   
 
     }
     // Hit Detaction 2
     void OnCollisionEnter(Collision collision) {
         if (collision.gameObject.tag == "Bullet" ) {
             H = H - (30 / Random.Range(1,3));
             Debug.Log ("HIT!");
         }
 
 }
     
     //Respawning 
     void SpawnMyPlayer(){
         PhotonNetwork.Destroy(Charac);
         H = 100;
         GameObject MyPlayer =(GameObject) PhotonNetwork.Instantiate ("Character" , Vector3.zero,Quaternion.identity , 0);
         
         
         MyPlayer.GetComponent<CharacterController> ().enabled = true;
         MyPlayer.GetComponent<CapsuleCollider> ().enabled = false;
         
         ((MonoBehaviour)MyPlayer.GetComponent("Movement")).enabled = true ;
         ((MonoBehaviour)MyPlayer.GetComponent("CharCamera")).enabled = true ;
         ((MonoBehaviour)MyPlayer.GetComponent("Health")).enabled = true ;
         
         MyPlayer.transform.FindChild ("Cam").gameObject.SetActive (true);
         MyPlayer.transform.FindChild ("Canvas").gameObject.SetActive (true);
 
         
     }
 
 }
 

the second

 using UnityEngine;
 using System.Collections;
 
 public class Network : MonoBehaviour {
     
     void Start (){
         Connect ();
     }
 
     void Connect (){
         PhotonNetwork.ConnectUsingSettings ("1.0.0");
     }
 
     void OnGUI(){
 
         GUILayout.Label (PhotonNetwork.connectionStateDetailed.ToString() );
     }
     
     void OnJoinedLobby(){
         Debug.Log ("OnJoinedLobby");
         PhotonNetwork.JoinRandomRoom();
     }
 
     void OnPhotonRandomJoinFailed(){
         Debug.Log ("OnJoinedLobbyFailed");
         PhotonNetwork.CreateRoom (null);
     }
     void OnJoinedRoom(){
         Debug.Log ("JoinedRoom");
 
         SpawnMyPlayer ();
     }
 
     void SpawnMyPlayer(){
         GameObject MyPlayer =(GameObject) PhotonNetwork.Instantiate ("Character" , Vector3.zero,Quaternion.identity , 0);
 
     
         MyPlayer.GetComponent<CharacterController> ().enabled = true;
         MyPlayer.GetComponent<CapsuleCollider> ().enabled = false;
 
         ((MonoBehaviour)MyPlayer.GetComponent("Movement")).enabled = true ;
         ((MonoBehaviour)MyPlayer.GetComponent("CharCamera")).enabled = true ;
         ((MonoBehaviour)MyPlayer.GetComponent("Health")).enabled = true ;
 
 
         MyPlayer.transform.FindChild ("Cam").gameObject.SetActive (true);
         MyPlayer.transform.FindChild ("Canvas").gameObject.SetActive (true);
             
     }
 
 
 
 
 
 
 
 
 
 the third 
 
 
 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Shooting: MonoBehaviour {
     
     public Text AText;
     
     public Transform Player;
     public Transform Cam;
 
 
     public Movement MoveScript;
 
     public AudioSource Reload;
     public AudioSource Fire;
 
 
     public float A;
     public float Ammo;
     public float Aclips;
     public float GunDam;
     public bool CanFire;
 
     private float Re;
     private float Ampk;
 
     void Start (){
     }
     void Intilize (){
         MoveScript = Player.GetComponent<Movement>();
     }
 
 
     void Update () {
 
 
 
         Ampk = MoveScript.Amhit;
         if(!Reload.isPlaying){
         if (A == 0 && Aclips > 0) {
 
             Re = Ammo - A ;
             Aclips = Aclips - Re;
             A = Ammo;
 
             Reload.Play ();
         }
         if (Input.GetKeyDown (KeyCode.R) && Aclips > 0 && A < Ammo) {
                 Re = Ammo - A ;
                 Aclips = Aclips - Re;
                 A = Ammo;
             Reload.Play ();
             }
             if(Ampk == 1 ){
                 Aclips = Aclips + Ammo;
                 Ampk = 0;
                 Reload.Play();
             }
         }
 
         if (CanFire == true && A > 0) {
             if (Input.GetButtonDown ("Fire1")) {
                 if (!Fire.isPlaying) {
                     Fire.Play ();
                     Shoot ();
                      
                 }
             }
 
 
         }
         AText.text = "A " + A + " / "  + Aclips;
     }
     void Shoot(){
         GameObject fire;
         A = A - 1;
         fire = PhotonNetwork.Instantiate ("Ammo" ,transform.position , Player.rotation , 0 );
         fire.GetComponentInChildren<Rigidbody>().position = transform.position + (GetComponentInChildren<Rigidbody>().transform.localPosition = new Vector3 (0.0f, 0.6f, 0.0f));
         fire.GetComponentInChildren<Rigidbody>().velocity = transform.TransformDirection (Vector3.forward * 100);
         Player.Rotate (Vector3.left * Time.deltaTime * 100);
 
     }
 
 }
 
 can anyone tell me what is the problem ..

and yes i did put the photon view thing

     }
