RPC called from another class?

Hello! I have this RPC, in another class called WaysOfWinning (creative name);

[PunRPC]
public void NextRound()
{
Debug.Log("Next round");
}

then in another script, I call this;

WaysOfWining.PV.RPC("AttackersWinBySendingUplink", RpcTarget.AllViaServer);

is that correct, or do i call;

WaysOfWining.PV.RPC("WaysOfWining.AttackersWinBySendingUplink", RpcTarget.AllViaServer);

TIA! :*
