Unity networking RPC problem- Photon

Hello guys,

I'm trying to call an RPC and it just isn't executing. If I do the exact same thing without an RPC it works fine but I need all the players to instantiate the text. Is there some reason why this wouldn't execute? I get no error message except this:

NullReferenceException: Object reference not set to an instance of an object

     private void GameStart()
     {
         photonView.RPC("SpawnText",PhotonTargets.All);
     }
 
     [RPC]
     public void SpawnText()
     {
         timer = PhotonNetwork.Instantiate(timerPrefab.name, timerPrefab.transform.position, timerPrefab.transform.rotation, 0);
         timerText = timer.GetComponent<TextMesh>();
         timerText.text = null;
         questionMain = PhotonNetwork.Instantiate(questionMainPrefab.name, questionMainPrefab.transform.position, questionMainPrefab.transform.rotation, 0); 
         questionMainText = questionMain.GetComponent<TextMesh>();
         questionMainText.text = null;
     }
 

Thanks!! Chris
