True enough, earlydean!

Probably the most successful approach is to enter the vipers' nest (oops, I mean the inspectors' office :D), codebook in hand, and express absolute puzzlement that you simply cannot find the relevant section - could they be of some help?

This approach has some subtle advantages. First of all, having the Code in hand shows you're serious. Asking for their assistance is as non-confrontational as you can get. Finally, the inspectors are likely to be out in the field, so you're likely to wind up speaking to the boss .... who will most likely make your troubles disappear. No bruised egos or hard feelings ... just a little misunderstanding smile
