[Zope] Folder Properties

How can I access a folder's properties from other documents? Example, the Home directory has properties like bg (#FFFFFF), fg (#000000), etc. that I want to use sitewide. I tried it and it works in that folder (/index_html works fine) but in other folders doesn't work /Hardware/index_html). How can I make it work? Do I need to use <dtml-in Home> each time I need to use it? It would be cumbersome and complicated when I'm using other INs for menues and stuff. Any ideas would be apreciated. -- Adrian Esteban Madrid Network Support, ATS Brigham Young University
