[Zope] Question on folders

[Daniel Yoo]

I'm trying to figure out how to access SQL methods within folders.  Here's
the directory structure I have so far:

dyoo
  queries
    sql_booklist (MySQL connection)
    sql_showTitles (SQL method)
  index_html



I've independently tested sql_showTitles to make sure it works.  In my
index_html, I'm having difficulty accessing stuff in queries:

<table>
<dtml-in queries.sql_showTitles>
<tr><td><dtml-var title></td></tr>
</dtml-in>
</table>


And Zope complains:

Traceback (innermost last):
  File /home/dyoo/Zope-2.1.4-linux2-x86/lib/python/ZPublisher/Publish.py,

KeyError: (see above)



I'm not quite sure, but is this a case where <dtml-with> is needed?  I
don't quite have a handle on the syntax of it.  Any help would be greatly
appreciated, thanks!
