Im not being able to fill up variables with RPCs

Hello there, I have been having some problems with RPC and variables... Its simple, in my game a player can create a server for 2 persons, and 1 person can connect to that server and play, the game its played by two persons, no more. So, for putting it simple, I have an Object (Lets call it OBJECTA) that holds variables trough a script, here it is the script:

 public class ADVOnline : MonoBehaviour {
     public string ForOnline1;
     public string ForOnline2;
     
     [RPC]
     public void LlenarFor1(string X) {
         ForOnline1 = X;
     }
     
     [RPC]
     public void LlenarFor2(string X) {
         ForOnline2 = X;
     }
 }

As you can see I have put two RPC functions in the script, so I can fill up those variables with a string that each player is going to pass to the function, that string are like t$$anonymous$$s: "4,3,4,4,4,4,4,2,2,3,4,4,1,1,2,3,3" etc... the t$$anonymous$$ng is that they are saved in PlayerPrefs with the name "SaveData1" (Obviusly, each player will have $$anonymous$$s own, and unique string, since each one has $$anonymous$$s save.

So in the script that connects server and client I have t$$anonymous$$s:

When I create a server:

 Network.InitializeServer(2, connectPort);
 Network.Instantiate(OBJETOA, transform.position, transform.rotation, 0);
 networkView.RPC("LlenarFor1", RPCMode.AllBuffered, PlayerPrefs.GetString("SaveData1"));

The problem is that, the variables in the OBJETOA doesnt fill up with the data (I checked and the string isnt empty), can somebody explain me WHY it isnt working? I cant understand what im doing wrong...

I have t$$anonymous$$s function for clients (Its all in the same script):

 networkView.RPC("LlenarFor2", RPCMode.AllBuffered, PlayerPrefs.GetString("SaveData1"));

And t$$anonymous$$s is the function in that script to combine with the another one:

 [RPC]
 void LlenarFor2(string X) {
         
 }
     
 [RPC]
 void LlenarFor1(string X) {
         
 }

So, anybody can help me or explain me what I am doing wrong?
