Hi Kevin, sorry i didn't post the whole thing, here it is. I do have
that in there. I am also narrowing it down even further than that. I am
inside another loop where I setting a "topiccode" and a "categorycode"

  [search-region
  prefix=resources
  list_prefix=resources_list
  search=|
  fi=resources
  st=db
  co=1
  sf=categorycode
  se=[scratch categorycode]
  op=eq
  sf=topiccode
  se=[scratch topiccode]
  op=eq
  sf=loscore
  se=[scratch score]
  op=<=
  nu=1
  sf=hiscore
  se=[scratch score]
  op=>=
  nu=1
  sf=inactive
  se=1
  op=ne
  ml=none
  |]

If my [scratch score] is 0, it grabs all the rows in "resources" table
that match topiccode and categorycode. even if the loscore is .5 for
that row...  If the score is .1 or something, then it seems to only grab
the row that is in "range". Is there something else that I am missing?

Thanks again
Rick
