Narrative:

First officer flying. Programmed FMC for fqmol arrival with altitudes, ie, hayed 18000 ft, sweet 7000 ft. We were given a clearance to 13000 ft MSL, then a crossing restr of sweet at 7000 ft. The first officer was in VNAV, went to descent page looking for capture to start down. I told him for the FMC to calculate a path he needed to put our altitude in the cruise page (13000 ft) so it would calculate a path to 7000 ft at sweet intersection. Instead of entering 13000 ft MSL he entered 7000 ft MSL which was the crossing restr. I told him what he did wrong. By this time we were past our descent point by a couple mi, so he selected level change, and used the spoilers. Depending on using DME or FMC position or crossing radial we were either 500 ft high or within 300 ft. There was no traffic on TCASII and approach control was not busy, nor was anything said. We probably were within the 300 ft. The first officer is new to the aircraft. He has approximately 100 hours as first officer on B737-300/500 and very little time in the -500 EFIS.

Title: FLC FAILS TO COMPLY WITH ALT RESTR.

Narrative: FO FLYING. PROGRAMMED FMC FOR FQMOL ARR WITH ALTS, IE, HAYED 18000 FT, SWEET 7000 FT. WE WERE GIVEN A CLRNC TO 13000 FT MSL, THEN A XING RESTR OF SWEET AT 7000 FT. THE FO WAS IN VNAV, WENT TO DSCNT PAGE LOOKING FOR CAPTURE TO START DOWN. I TOLD HIM FOR THE FMC TO CALCULATE A PATH HE NEEDED TO PUT OUR ALT IN THE CRUISE PAGE (13000 FT) SO IT WOULD CALCULATE A PATH TO 7000 FT AT SWEET INTXN. INSTEAD OF ENTERING 13000 FT MSL HE ENTERED 7000 FT MSL WHICH WAS THE XING RESTR. I TOLD HIM WHAT HE DID WRONG. BY THIS TIME WE WERE PAST OUR DSCNT POINT BY A COUPLE MI, SO HE SELECTED LEVEL CHANGE, AND USED THE SPOILERS. DEPENDING ON USING DME OR FMC POS OR XING RADIAL WE WERE EITHER 500 FT HIGH OR WITHIN 300 FT. THERE WAS NO TFC ON TCASII AND APCH CTL WAS NOT BUSY, NOR WAS ANYTHING SAID. WE PROBABLY WERE WITHIN THE 300 FT. THE FO IS NEW TO THE ACFT. HE HAS APPROX 100 HRS AS FO ON B737-300/500 AND VERY LITTLE TIME IN THE -500 EFIS.
