  Here's a very tricky error that almost all newbies encounter.
  Imagine you have a DTML Document called *zooName*.  This
  document contains an HTML form like the following::

    <dtml-var standard_html_header>

      <dtml-if zooName>

        <p><dtml-var zooName></p>


        <form action="<dtml-var URL>" method="GET">
          <input name="zooName">
          <input type="submit" value="What is zooName?">


    <dtml-var standard_html_footer>

     Why wouldn't the form action code use a Zope object name instead of the URL variable? I thought that in one
     of the previous examples form actions were more object-oriented than this.
