Need help with walkthrough

[Kattey]

Hello guys!
I've just completed "Antichamber". But I can't complete one section (or level) (it's called "Connecting the pieces").
Does somebody have any idea what can I miss?

I think thats the part with the invisible stairs right?

Start the level and try to get above the invisible stairs. Theres a third story floor, if I remember correctly.
