[Zope] Help: DTML lookup problem (subfolder specialization)

Hi, I want to have a logo at the top of each page, so what I've done is reference a "logo" method from my "header" method. Subfolders should be able to redefine a new "logo" method if they want to. This only works, though, as long as there's a dtml_index in the subfolder. If, though, the subfolder doesn't define one, and a parent's dtml_index is found, then the *parent's* "logo" is also used, not the one in the child folder. Is it possible to do what I want? Here's a hierarchy view: PARENT: logo index_html (Calls header which ref's logo) SUBFOLDER: logo ...This set up is not working for me. Is there some way to make it work? That is, when viewing the subfolder, it's logo would get found and used? Thanks, Robb
