[Photon]PhotonView with ID 6 has no method "Addplayer" marked with the [RPC](C#) or @RPC(JS) property! Args: Int32, String

I am trying to make a scoreboard in my game. When i call the rpc for "Addplayer" and "Addscore" this comes up: PhotonView with ID 6 has no method "Addplayer" marked with the [RPC](C#) or @RPC(JS) property! Args: Int32, String I simply need help because im loosing sanity here, heres my code:

   [RPC]
         void Addscore(int kill,int Assist, int death,int ID) {
             foreach (Players x in playerscores) {
                 if (x.ID == ID) {
                     x.kills = x.kills + kill;
                     x.Deaths = x.Deaths + death;
                     x.Assists = x.Assists + Assist;
                 }
             }
         }
         [RPC]
         void AddPlayer(int ID, string name) {
             playerscores.Add(new Players(ID, name,0,0,0));
         }
         

and here:

 void OnJoinedRoom() {
 
         Debug.Log("OnJoinedRoom");
         SpawnMyPlayer();
         //PhotonView.RPC("Addplayer",PhotonTargets.AllBuffered ,PhotonNetwork.player.ID,PhotonNetwork.player.name );
         this.gameObject.GetComponent<PhotonView>().RPC("Addplayer",PhotonTargets.AllBuffered, PhotonNetwork.player.ID,PhotonNetwork.player.name );
     //    AddPlayer(PhotonNetwork.player.ID,PhotonNetwork.player.name );
     }
     void SpawnMyPlayer() {
         Debug.Log ("SpawnMyPlayer");
         if (spawnSpots == null) {
             Debug.LogError("?");
             return;
         }
         SpawnSpot mySpawnSpot = spawnSpots[Random.Range (0, spawnSpots.Length)];
         GameObject myPlayerGO = (GameObject)PhotonNetwork.Instantiate("Player", mySpawnSpot.transform.position, mySpawnSpot.transform.rotation, 0);
         standbyCamera.enabled = false;
         this.gameObject.GetComponentInChildren<AudioListener>().enabled = false;
         ((MonoBehaviour)myPlayerGO.GetComponent("MouseLook")).enabled = true;

         myPlayerGO.GetComponent<MeshRenderer>().enabled=false;
         Transform Direction =myPlayerGO.transform.FindChild("Direction");
         Transform camera=myPlayerGO.transform.FindChild("Camera");
         //Transform Model=myPlayerGO.transform.FindChild("Model");
         camera.gameObject.SetActive(true);
         Direction.gameObject.SetActive(true);
         //Model.gameObject.SetActive(false);
         myPlayerGO.rigidbody.useGravity = true;
         myPlayerGO.rigidbody.isKinematic = false;
