Here's the method that calls that method: <dtml-var "get_storys">
Why the quotes?
try <dtml-var get_storys> instead
But then I get the following weird error: Traceback (innermost last): *snip*
(Object: objectValues('Story')) File /root/Zope-2.2.0-src/lib/python/DocumentTemplate/DT_Util.py, line 337, in eval (Object: sequence-index == 0) (Info: index) File <string>, line 0, in ? NameError: (see above)
I am fairly new to zope, but this seems pretty weird, especially the method returning its dtml source.
And you've been caught by one of the most common (and understandable) newbie mistakes. (o8. 'sequence-item' is not a valid Python name. To Python it looks like " sequence - item ", the mathematical expression. This is a holdover from days of old, and not much has been done to deprecate it (all my shouting, and that of others, has so far come to naught.) <dtml-var sequence-item> will work, because that is in Zope Land... no quotes. <dtml-var "_['sequence-item']"> is the Python Land equivalent. the _[] name space lookup is your friend for this sort of problem. <dtml-if "sequence-index < (numStories - 1)"> should be written as: <dtml-if "_['sequence-index'] < (numStories -1)">

I guess I should really try to rally people to send this to the collector... Have a better one, Curtis Maloney. <dtml-var standard_work_disclaimer>
