[Zope] calling external script from index_html

[Christopher Quinn]

Hello list,

just getting going and already belly-flopped at the first hurdle.
In a folder holding the external method object, an index_html 
referencing it via <dtml-val myscript_func>
does not appear to run the script, while a dtml method created in the 
same folder and making the same reference does run ok. I tried moving 
the external method object into a higher level folder in case it somehow 
was not in scope, but to no avail.

What is the correct way to make external scripts available to index_html's?

Cheers,
Chris Quinn
