Kingdom Hearts Hollow Bastion help!

Ok, I've finally got KH1. And I'm a little stuck in the castle in Hollow Bastion.
After you beat Riku (the first time, if there is more than one time), and you have to find the pieces that fit into that door. I can only find one of the pieces (the bottom one). I found the Lift Stop, but I don't know where to go from there. The lift goes to this ledge, and there's nowhere else to go. Can someone help me, please?

 

If you go through the library you'll find another door into the entranceway. This is where you'll earn most of your emblem peices. Just experiment arround with things up there. I you examine everything they basically tell you what to do.

 

Did you finish the extraordinarily long library puzzle? Put all the books in order and you will get a piece. There is a fire puzzle in the next room.

The lift should go to a room that gives you a piece. Simply beating Riku should give you a piece.

Am I missing one?

 

What you need to do is continue the library puzzle until you've unlocked the door at the top of the stairs. Go through that door. You'll be at a circular area above the hall where you fought Riku. Here's what you need to do:

-Light all the candles.

-Use Red Trinity on the stone.

-Show one of the statues your "crushing power" by breaking the two pots on either side of it.

-Move the other statue to the right.

There is also an electric panel up there that you have to shock to activate. All it does is set some moving platforms in motion, but if you activate it, it will be easier for you to grab one of the emblem pieces.

It should be easier to ascend the heights of the castle from that point onward.

 

Thank you! :)
