Prince of Persia Warrior Within Help

[sub780lime]

Ok, so i need help, and i cant find an answer in any walkthroughs so i turn to you guys. I am in the southern passage of the Reach the Hourclass Chamber part of the game, pretty early on in the game. I have made my way around the room. wall jumped back and forth to get to a higher point. i am than to shimmy(sp) around and jump to a beam and than jump to a hole in the wall where i would than save. i can get all the way to jumping to the beam, but there is no whole in the wall, i can jump over there and find the groove, and i can see how this could be turned into a whole if some pushed the block out, but its currently not there, what have i missed, one walkthrough said, pull yourself up through the hole the the Dahaka made, but that part never took place in my game while ive been in this room, i got here, so i assume i did everything in the previous room since i dont believe i can get back here anyway, but i just dont know what i have to do to get that piece pushed out so i can pull myself up through that hole, anyone have any idea what im talking about and can help. thanks in advance!
