Third Party problem with photon

i want to use RPC for calling function in remote player, my problem is that this function call also in my game and also the remote player, what i missing ?

this the code

void Start () {
GetComponent<PhotonView> ().RPC(
"PrintSomething",
PhotonTargets.Others,
null
);
}

[RPC]
void PrintSomething()
{
// UnityEditor.EditorUtility.DisplayDialog("Big", "you win the game !!", "Ok");
Debug.Log ("111");
}

the code is attach to prefab that have PhotonView

 

Is PrintSomething() in the same script as start()? I needs to be in the same script.

 

To elaborate on this: It has to be in the same script because GetComponent<PhotonView> ().RPC(...) will get the PhotonView of this Game Object and "target" the RPC to this PhotonView / GameObject.
So actually, PrintSomething can be in another script, but has to be on the same (target) PhotonView / Game Object.
