Thanks for your responses! Laura, I tried using that as the path, but it did not work. I'm just confused as to why the custom page types are changing a path that is in the master template. I can't find anything in the path documentation to help me always start at the root page, no matter what the page type is. I need the category and subcategory pages to be custom page types so they can have custom fields.
Brenden, what do you mean by setting the hierarchical transformation to a specific class? Where can you set that?
