[Zope] Help needed with news articles

Basically I want to create a page listing the last 4 articles from a Zope folder. The articles need a publish from/to field, title and (dtml) text. I somehow need to be able to find and display the article from another dtml document. I read many FAQs and tried working with zcatalogs, but somehow I am not getting there. It is probably not so difficult. If there is somebody how can help me or give me a link to a clear explanation or example I would be very very grateful. Thanks ! Taco
