Narrative:
ATC told us to descend to cross 25 NM north of julian VOR at FL240. We were high by 5000 ft or 6000 ft. I think if we had had both vors tuned to julian, there would have been less of a chance of missing the descent point. This was a new route, las to san, and the omega route wasn't preprogrammed. The captain was distraction by trying to program in a fix and the box wasn't taking it. I was distraction by calling in our ETA to san and getting the gate assignment.
