Narrative:

After liftoff from runway 24 we were switched over to departure. The PF was the first officer and the captain the PNF. While switching over to departure the first officer noted a problem with the #2 FMS. I checked on with new york level 1500 ft; and then proceeded to check the #2 FMS. Then comes the confusion. The first officer asked what the next fix was and I stated at 4.5 DME then climb to 2000 ft. Next thing I know the aircraft is level at 2000 ft at 3 DME. New york saw it as fast as I did and noted the error. There were no traffic conflicts and ATC stated no harm no foul just don't let it happen again. The confusion was what was asked and what was heard. We have discussed it and decided the best action would be to read back all questions to relieve confusion.
