There you go, takes you straight to the cheats.
I think you must have just looked up cheats for the first Sims game.
But that cheat you got sounds very similar to the first Sims game, are you sure you've looked up the correct game?
I don't know where you got your cheat from, but try 'www.cheatplanet.com' and see what they have, they're very reliable for the most part.
