Narrative:
West of scole at FL350; given a descent to FL330 to cross scole at FL250. We descended through FL330 but got distraction and did not increase descent to be able to cross scole at FL250. We believe ATC gave us relief by issuing a new crossing restr of geela at 250 KTS and 11000 ft just prior to scole. Go all the way down on a 2-PART clearance.
