[Zope] view index_html of zlass

Zope version 2.1.6 on redhat 6.2 using apache integration zia zope.cgi I have created the cdclass example in the zope developer guide on zope.org. I have created a dtml document in the cdclass zclass with <dtml-var id> and <dtml-var title> statements in it. The zclass instance is called mycd. When I try to view the instance called mycd. i get zope error "You are not authorized to access title_or_id. " I made sure all permissions for anonymouse are set to view. What could I be missing. Thanks for your help. cj technology@mylinuxisp.com
