Narrative:

Cleared to cross jokur intersection at FL240 per STAR (level was at FL290). I missed the crossing restr due to activity in the cockpit. Never prompted by center. Next call (10 mi past jokur) was 'cleared to cross whigg at 12000 ft). It was then that I realized that I had missed jokur's restr. Corrective action: have all the non essential cockpit stuff taken care of before or do later on a very short flight.
