So...... Hi, nice to meet you

Move
Anyways, i have a little question here. I dled a video from here i think and it was made by a clan and it was about super bouncing on foundation. They crouched in the corner of that little building in the middle near where you get the sword. Then they ran out, up the stairs of one of the sides, and jumped off onto a crack in the tiles below and bounced super high. I tryed this, i even put my comp screen beside my tv and follow what the guy was doing exactly but i couldnt get it.
What im doing
So i would make sure im in the right corner like in teh video, i would crouch and look at the wall and walk into it and keep push, then i would stand up and then go up the stairs and jump off on to the crap and... nothing.
What im i doing wrong guys this move looks crazy sick

Btw: this movie is by H2AA, and its called Foundation Superbounce.
Video: I need an uploader to show yeah, putfile needs to register now

Thanks in advance Jamie
