Anyone out there know anything about the cheat codes for the Sims1? preferably the "move_objects" code.

I have Sims (1) Deluxe edition, running XP. On the 6th neighborhood, the biggest (most expensive lot) I always have guests who come over and end up stuck for no reason, inside, and outside the house. Yes I have moved chairs, walls etc., around hopeing they would move. I can't even click on the guests. Once I used the cheat code "move_object on" or so I thought. It keeps telling me I an using the wrong parameter. HELP! Otherwise I have to move out of the house and rebuy it which will take hours to refurnish. Anyone know what kind of bug this is and how I can keep it from happening? Otherwise, my friends/guests all die right there in that one spot. Thanks!
