Narrative:
Coming in to atl on the lgc arrival, we were given a crossing restr of 40 mi out at 12000 ft. We were about 64 DME out, so I told the first officer to get the altitude first and then the speed. At this time I went off frequency to get the ATIS. When I returned we were level and on speed. Our next radio call was a clearance to 8000 ft and we started descending. At this time we discovered that the first officer had leveled at 14000 ft, not 12000 ft. Since we were passing 11000 ft, we thought we were ok. This approach has both 12000 ft and 14000 ft clrncs on it and I believe if it had one or the other this would not have happened.

Title: B737-200 CREW LEVELS OFF AT WRONG ALT DURING ARR PROC. APCH PROC SHOWS 2 DIFFERENT ALTS FOR THE PROC, RPTR USED THE WRONG ONE.
Narrative: COMING IN TO ATL ON THE LGC ARR, WE WERE GIVEN A XING RESTR OF 40 MI OUT AT 12000 FT. WE WERE ABOUT 64 DME OUT, SO I TOLD THE FO TO GET THE ALT FIRST AND THEN THE SPD. AT THIS TIME I WENT OFF FREQ TO GET THE ATIS. WHEN I RETURNED WE WERE LEVEL AND ON SPD. OUR NEXT RADIO CALL WAS A CLRNC TO 8000 FT AND WE STARTED DSNDING. AT THIS TIME WE DISCOVERED THAT THE FO HAD LEVELED AT 14000 FT, NOT 12000 FT. SINCE WE WERE PASSING 11000 FT, WE THOUGHT WE WERE OK. THIS APCH HAS BOTH 12000 FT AND 14000 FT CLRNCS ON IT AND I BELIEVE IF IT HAD ONE OR THE OTHER THIS WOULD NOT HAVE HAPPENED.
