I want to be able to do something like this:

First off, the <dtml-with "_['sequence-item']"> is superfluous, the <dtml-in> tag automagically pushes sequence-item on the top of the namespace stack. Second, there is the python builtin function _.len() that you can use to determine the size of a sequence (untested):: <dtml-let sequence="whatever()"> <dtml-in sequence> <dtml-if "_.len(sequence) == 1"> one </dtml-in> </dtml-in> </dtml-let> The <dtml-let> is useful because it caches the possibly expensive whatever() operation into a 'local' variable. -Michel
