It would be *very* helpful to give the exact error message you received.

What you see is expected behavior. Saving an off file does not check to
see if parmeters are available for all the types of bonds you have in
the molecule. Having missing parameters only shows up when you execute
"saveamberparm". You will probably need to create a frcmod file with the
appropriate parameters in it. Since you don't say how you constructed the
CHN0 unit in the first place (or what it is), it's hard to give any more
specific advice.
