RPC call on other scene,NetworkView RPCs in other scene,

Hello... i'm making a multiplayer game... and i have a lobby system, where the client connect on the server to get more info about the connected players on this server and stuff. It works, but when the server is already in game, and some client want to enter in this lobby, the client RPC call don't find the server script, that send the RPC to the client with the informations. The menu is a scene, and the in game is an other scene, and i don't destroy the gameObject that have the RPC script when load... the client just can't find it... Is there some solution for that?,
