What about the Zope Book or

It is *never* "someDTMLfunction([...])".

You need to split things into different subtasks. Otherwise, you will loose:

Again:

  *  you access objects (and their attributes) via the bindings

  *  you interate over sequences with: "for XXXX in SEQUECNE"

  *  you call methods according to their API (see embedded online
     help -> Zope Help -> API reference)

     Especially, you do not call DTML objects with a list
     of strings as single parameter (more in
     "calling DTML objects" in the above reference.
