Stuck at Midgard Serpent

[rynoz7]

Hi,
I have gotten three of the stone slabs, but I cannot figure out how to get to the four door. The door is the one directly to the left of the entrance we came in on the motorcycle. I can somewhat see what I have to do, but I can't figure out how to get started. Please help!!!

Look over where there are the pillars (I believe it is to the right of that door). Go there and find a small space in the wall. You have to bounce/jump there back and forth to get up... Then you can jump on the pillars to get to the door
