Narrative:

We received notoc. It was approved. Went on with remaining duties. Copilot read close out and with rarely getting notoc copilot missed the fwd. No. Aft no. I did not check ground employee's work except aircraft weight then mind to runway then hw/tw. Cause: both out of practice because the system is so reliable it almost always matches. Suggestions: continue to cross check close out with all paper work including notoc.
