[Zope] New to Zope....

... and totally lost into the depth...

Hi,

I´m struggling with Zope for a few days and so far it looks as it
could do the job. But sometimes I feel like never used a
(computer)-language before. It´s so different. Maybe I havn´t found
the way to think for Zope...

The Tutorials are a bit rare or too basic and the documentation is a
bit theoretically (IMHO).

My way to learn ist "learning by doing" but now I´t totally stuck
(maybe its Zope or my brain...).

I want to do a site with a title on every page in the different
folders which differs only in
one word (in real a graphic). So I thought of using a folder property
which names this word. I include the title with <dtml-var Titel> and
in there is a (html)table with the title and one is <dtml-var titel>
where titel is the property of the folder. This property has the value 
which points to the correct graphic. But it seems that because the
"Titel" DTML is in the root of my site it doesn´t know of the folder
property "titel" and I get an error :

          Error Type: KeyError
          Error Value: titel

I was also searching for a way to pass some arguments to a DTML
function, but with no success. Maybe I´m trying the totally wrong for
attaining the desired result. Any suggestion is very welcome so I can
go further with my Zope experiments.

Thanks,

Carsten Wartmann.
