Narrative:

Arrival into new york jfk on the plymm arrival. Talking to ZBW. Cleared to cross trake at FL240. I was flying. Captain set up crossing restr in CDU FMC. Aircraft was operating in VNAV. Center changed crossing restr and cleared us direct parch to cross 20 mi east of parch at FL240. Captain reset direct parch and 20 mi east of parch in CDU/FMC. Did not set FL240 in FMC. Aircraft was still in VNAV for an automatic descent. We assumed that we had FL240 set in because we had set up FL240 for trake. Approaching 20 mi east of parch we were asked by center if we were going to make the restr. We said that it will be close. Center then gave us a direct to rober intersection to cross at 9000 ft which we put in the FMC and both verified and made. We both learned that when any entry is made in the CDU/FMC it should always be verified by the PNF.
