<dtml-in objectList mapping> <dtml-var objectMethod> </dtml-in> Can I call objectMethod on each of the objects.It popped up the Authentication Window when I tried to access the object method with mapping,but the other object attributes are accessible.

"Authentication Window popping up" suggests that reading Brian's Zope security paper (-> zope.org) may help. Reading URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html may help you to understand when/why you use "mapping" as attribute for "dtml-in" or "dtml-with". Dieter
