[RPGXP] Need Help For Call Of Duty Game!

[Scripter1123]

Hi People,
I Need Some Help With My Game  It's A Remake Of Call Of Duty: Nazi Zombies, And Hopefully It Is Going To Be Online Multiplayer. 
But On The Title Screen, I Have Changed The Text, To Nacht Der Untoten, Zombie Verruckt, Shi No Numa, Der Riese, And Of Course, Quit. I Know The Command For Quit, (command_shutdown), But For The Others, I Would Like It To Start A Different Map For Each Option. But I Do Not Know The Commands. I Have Tried command_load_map_Zombie Verruckt, command_load_map_001, EVERYTHING!!!

Please Help!
