should be:

<dtml-if "_[Category][:2] <> 'No'">
  <dtml-call "REQUEST.set('desc[idx]', _[Category])">
  <dtml-call "REQUEST.set('desc_qty[idx]', qty)">
  <dtml-call "REQUEST.set('idx', idx + 1)">
</dtml-if>

Assuming that Category contains an Id, and not the string you are trying
to examine and store, that is.  If Category is the string, leave off the
'_[]'s.
