Using Membership with Directory

We want to create different levels which we have already done in Membership. Based on the membership level, 1. one can either put a little info in our directory, 2. a little more info in our directory or 3. a lot of info in our directory. However, we are having trouble getting directory to recognize the levels. No matter what we do, the results stay the same for all levels. We printed out the "manual" but it doesn't quite seem to answer our needs. Please advise.
