Sims 3 Cheat Help

I dont usually cheat at games but right now I wanna have fun with one of my sims. I got some cheats to work like Motherlode and a couple others but 2 of them I cant do even though most (all) websites say that it is a cheat. If some one can give me instructions on how to work the cheat ''Shazaam'' and ''Set Career'' which is the one for level not which career, then that would be great :)
