Narrative:

Given a crossing restr to descend to FL310 from FL390 by 70 mi west of jnc. Aircraft had just passed jnc and so jnc was not in the FMS anymore. I looked at the flight plan and looked on the wrong lines to figure where 70 mi from jnc would be in relationship from the next point on the flight plan (helpr). I set up the descent to arrive early. Well, my calculation was incorrect and I was still between FL330-320 when at 70 mi west of jnc. Center called and informed me of the situation after the fact. They said that there was no conflict. I learned how to properly figure these problems out for future use. I learned a good lesson. I'm fairly new to the B767 and FMS work. It won't happen again.
