[Zope] ZPT/TALES question

[Tim Moore]

OK, so my site has a standard METAL template that all of the templates
in the site use.  It contains navigation links and such.  I want one
of those links to always go to the index_html page that's at the same
level of the hierarchy as the standard template macro.  The problem is
that if I use a path like "here/index_html/absolute_url", then "here"
is considered relative to the template that uses the macro, not the
one that defines it.  Can anyone offer any suggestions?

thanks!
