Scene Selection

I have a first person shooter. It has multiplayer and is working. everything is fine. i have my maps and everything. I just want to make a list of maps that you can choose from. So when you click on multiplayer it loads a scene that would be the map select. then it would load the lobby with a list of all the servers using that map. Something like thisjust it loads the selected scene scene after i select the map and press a button. I know some code (only java-script and c#) i prefer java-script but you know.......if anyone could help me ill give u some credit in the game.
