nodes

I love the way you can use a phrase like "People who live in %" using the regular Drupal profile module and then by clicking the link, get a list of all users who live in %. I'm trying to get the same thing happening with profiles as nodes. I've tried using CCK taxonomy fields in both the Node Profiles and the Bio Modules. It almost works, but only intermittantly. Sometimes I get the message "There are currently no posts in this category ..." other times, some users will show up and others won't - even when they have been tagged with the the term.
