And you've been caught by one of the most common (and understandable) newbie
'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
<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...
