[Zope] Newbie: dtml-unless

I'd like to list the content of a folder, except if it is the standard_html_header or footer. I use this code: <dtml-unless "'id' == 'standard_html_header'"> <dtml-unless "'id' == 'standard_html_footer'"> <dtml-in expr="foldername.objectValues()"> <a href="<dtml-var absolute_url>"><dtml-var id></a><br> </dtml-in> </dtml-unless> </dtml-unless> It works except of the fact, that standard_html_header and footer are listed anyway. Can anybody point me into the right direction please?
