Photon Unity Networking Score Issue

I am a begineer photon user. I have a problem by integrating it. The question is I have a prefab "spinner" with child canvas showing score and it has a player script [code downwards]. when other clients instantiated then the player only can see its own score but other client's score shows 0 on every player. Help..!

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class Player : Photon.MonoBehaviour { Camera playerCam; Text scoretext; // Use this for initialization int score; int id; void Awake() { score = 0; id = PhotonNetwork.player.ID; Debug.Log (id); // DontDestroyOnLoad (gameObject); // //playerCam = GetComponentInChildren (); // // if (!photonView.isMine) { // //// playerCam.gameObject.SetActive (false); // } scoretext = GameObject.Find ("Spinner(Clone)/CanvasSpinner/Panel/Score").GetComponent ();

 }



 void OnTriggerEnter2D(Collider2D col){
     
     if (col.gameObject.tag == "enemy") {
         Debug.Log ("collision");
         if (photonView.isMine) {
             score += 1;
         
             scoretext.text = score.ToString ();
             GetComponent<PhotonView> ().RPC ("UpdateScores", PhotonTargets.All,score);
         }
             Destroy (col.gameObject);

 GetComponent<PhotonView> ().RPC ("UpdateScores", PhotonTargets.All);

     }





 }

 [RPC]
 void UpdateScores(int test) {
     
     scoretext.text = test.ToString();
     Debug.Log (scoretext.text);
     //Keep in mind that it doesn't matter that 'username' and 'score' above are the same as when you send it; they just need to both be the same Type of variable, such as string and float.
     //You now have the username and the score on other clients. Do your 'update' stuff here.
