Narrative:
While cruising at FL370, ZJX gave us a crossing FL240 restr 40 NM south of florence, at the same time flight attendant 'a' entered the cockpit with some type of problem in the passenger cabin. I was distracted and did not verify. The crossing restr was set in the FMC correctly. Apparently the assigned altitude was not set correctly, resulting in flying by the 40 NM fix south of florence several thousand ft above FL240.

Title: A XING RESTR WAS SET INCORRECTLY IN THE FMC RESULTING IN AN ACR FLC'S ALTDEV OF SEVERAL THOUSAND FT.
Narrative: WHILE CRUISING AT FL370, ZJX GAVE US A XING FL240 RESTR 40 NM S OF FLORENCE, AT THE SAME TIME FLT ATTENDANT 'A' ENTERED THE COCKPIT WITH SOME TYPE OF PROB IN THE PAX CABIN. I WAS DISTRACTED AND DID NOT VERIFY. THE XING RESTR WAS SET IN THE FMC CORRECTLY. APPARENTLY THE ASSIGNED ALT WAS NOT SET CORRECTLY, RESULTING IN FLYING BY THE 40 NM FIX S OF FLORENCE SEVERAL THOUSAND FT ABOVE FL240.
