getting finance charges to work

We want to start implementing finance charges. Three of us have tried everything suggested in the peachtree docs (default customer setup, apply finance charge, etc). However, it seems only accounts over 1
year past due get a finance charge. We must be missing something obvious. Any advice? Thanks!
