This mod displays lists of members via classes.  The display side
works great (see http://www.uptownminneapolis.com/art-fair/  (dropdown
on left).  However, on the admin side, I can only list the first 20
items (our of 100+).  There are links to next page of listings (pg 2,
3, 4, etc), but they all yeild a page that says "no listings found". 
This makes it impossible for my client to edit/delete listings beyond
the first visible 20.  I know a hack could fix this, but not a php
coder.  Any help would be...well, appreciated.  This is a production
site to go live immediately.
