I have been away from Zope for about a year or so. I used to be able to comment out blocks of code with: <dtml-comment> code to commented out </dtml-comment> this doesn't work in the code below? <dtml-comment> <h2>Sibling Links</h2> <div tal:define="siblings here/siblings.py"> <ul tal:condition="siblings"> <li tal:repeat="folder siblings"> <a href="folder" tal:attributes="href folder/absolute_url" tal:content="folder/getId">folder id</a> </li> </ul> <p tal:condition="not:siblings"><b>There are no courses scheduled at this time.</b></p> </div> </dtml-comment> The code between the comment open and end tags is still displayed, what am I doing wrong? Zope Version (Zope 2.5.0 (binary release, python 2.1, linux2-x86), python 2.1.2, linux2) Python Version 2.1.2 (#1, Jan 25 2002, 13:17:56) [GCC 2.7.2.3] System Platform linux2 Thanks, DR
