The room number thing just stays at zero, even though i am going to management window rooms, then room furniture still doesn't work.. Eh, i'll figure it out.
Once you have open the management window -> rooms -> room in which you want to add the object (its a "1", or a "2", etc) -> furniture, it says "click on the objects to add the furniture". Then, just go to the room label while that window is open and click it.
