Captain engaged FMS/autoplt so as to utilize VNAV and LNAV simultaneous with a leveloff. Given heading change for spacing, aircraft failed to level off/capture the FL210 setting. We did the double hand point at the MCP, saw LNAV and VNAV on the FMA (or so we thought). No contact from ARTCC as to altitude deviation. Figured it was something we did as a crew, not the aircraft's fault. Captain had 27 hours in aircraft, I had 175.

Narrative: CAPT ENGAGED FMS/AUTOPLT SO AS TO UTILIZE VNAV AND LNAV SIMULTANEOUS WITH A LEVELOFF. GIVEN HDG CHANGE FOR SPACING, ACFT FAILED TO LEVEL OFF/CAPTURE THE FL210 SETTING. WE DID THE DOUBLE HAND POINT AT THE MCP, SAW LNAV AND VNAV ON THE FMA (OR SO WE THOUGHT). NO CONTACT FROM ARTCC AS TO ALTDEV. FIGURED IT WAS SOMETHING WE DID AS A CREW, NOT THE ACFT'S FAULT.
