I defined an external method "build_adn" which I can call from a DTML-document. How do I call it from a Python script?

I tried e.g. "return build_adn (zone)", but it did not work.

The script needs to know what namespace to look in. To tell it to look up build_adn in the calling context (the folder or object from which you called the script), do this:

return context.build_adn(zone)

The available namespaces (context, container, script, traverse_subpath) are described in the Zope Book. Go to the chapter on "Advanced Zope Scripts", section "Using Python-based Scripts", item "Binding Variables".

And how do I call a DTML-variable (object?) defined with <dtml-let var=...> from my script? context.var, container.var, script.var don't work. I want to get the variable's value regardless if it is defined via dtml-let or set within the request (from an HTML form). Peter
