Narrative:

Programmed the crossing restriction as ten north of fwa; when it should have been ten south; at FL240 (fwa/10 versus fwa/-10). Failed to identify the programming error until ATC pointed out that we looked high; issuing a traffic alert. I have been on an a.M. Line this month and last. The day began with a late show time and was not scheduled to end until well after dark. Due to the late aircraft arrival; another lengthy delay for late connecting bags; a complicated mechanical issue; an associated maintenance delay and unscheduled swap; the already busy six-leg day became much more involved. Due to the short nature of all the legs and rapid tempo; climbing straight into descent; we both were quite worn out by the end of the day. Lobby time was in the morning. The prior day; lobby time was four hours earlier. We have a.M. And P.M. Trips for a reason; so pilots aren't bouncing between sleep cycles during the pairing. Unfortunately; that is exactly what we were scheduled to do. Keep pairings within the typical a.M. And P.M. Footprint. If the day is stretched; don't schedule a six-leg day.

Title: B737-700 flight crew reports programing the FMC for ten north of the fix instead of ten south as required; resulting in a missed crossing restriction. Fatigue was cited as a factor in the incident.
