[Zope] Indirect addressing

[Ragnar Beer]

Howdy Zopistas!

I have a directory structure like this:

+ myfolder
	index_html
	my_external_method
	dtml_method_1
	dtml_method_2
	...

In index_html I want to include either dtml_method_1 or 
dtml_method_2, ... (one method for every week of year). 
my_external_method tells me which dtml_method to include.
This would logically be handled with "<dtml-var <dtml-var 
my_external_method>>" in index_html but this doesn't work.

How could I get this working? Any ideas?
