[Zope] Zope Syndication

Further to my query on getting the zope news.rss to display, I got it to display on my browser by removing the line with <dtml-var "channel['title']">. I think this line is supposed to show the channel title, but some reason zope is not accepting this syntax. I anyone knows how to get past this syntax problem, please let us know. Thanks, Ot Ratsaphong
