Ok, for all of you having problems with it... it's simple. When you enter the place, just stand there by the door... don't move. If you move too far in without the combonation, you'll have to leave and come back in. So, if your standing there, just look a little above your character, and you SHOULD see symbols. Once you memorized them, step forward, light the correct oblisks(?) , and POOF... OKA'S CHEST! :-D
