Custom Games

I just looked in the Community thingy that I found in the game and I went to Custom Games TAB, I found this one saying Zombies+Heli then another one saying Zombies and more interesting things, I save them to my file share go to Combat Training, Game Mode but it's not there, at least that's how I think it should be I'm probably wrong because it doesn't come up so could you tell me how to load them up ? Thank you

you have to got to private match then got to change gametype , then u go to personalized gametypes then press load on the gametype u want and start match thats how i do on ps3
