Network Chat not sending messages to other clients

I'm having a problem where my network chat script isn't sending the messages for to or from other players. :/ here is the script -

 var             mySkin : GUISkin;
 var             userName : String;

 private var     windowRectT = Rect (10,310,700,20);
 var             scrollViewVector : Vector2;
 private var     outputText : String = "";
 private var     inputText : String = "";

 function OnGUI () {
 if(networkView.isMine){
     GUI.skin = mySkin;
     windowRectT = GUILayout.Window (0, windowRectT,ChatWindow, "Chat");
 }
 }
 function ChatWindow () {
  GUILayout.Label ("User Name:");
  userName = GUILayout.TextField (userName);
  GUILayout.Label("Message: "); 
  scrollViewVector = GUILayout.BeginScrollView (scrollViewVector);
  GUILayout.TextArea (outputText);
  GUILayout.EndScrollView();
  GUILayout.Label ("Chat:");
  inputText = GUILayout.TextField (inputText); 
     if (GUILayout.Button ("Send")) {
         networkView.RPC ("SendChat", RPCMode.All, userName + ": " + inputText);
         inputText = "";
     }
     GUI.DragWindow (Rect (0,0,1000,1000));
  }
 @RPC
 function SendChat (text : String) { 
 if(networkView.isMine)
 {
 Debug.Log("chat sent!!!");
     outputText += (text + "\n"); 
 }    
 }

Thanks for the help everyone!

(Anyone can feel free to use this in there game if needed as a base code for chat, but if you find a fix please post it. Thanks!)
