To do what you want, you probably want something like:

Erk, maybe this: <dtml-call
"manage_changeProperties(counter_value=getProperty('counter_value',getProperty(counter_starting_value,0)-1)+1)">

Words simply cannot express my gratitude. Can you clue me in a bit more on the functions you called. Looks like they are manage_changeProperties(), getProperty(). I'm guessing these are both Python functions. Where are they documented, so I can learn more? You mentioned that (1) DTML is not a programming language, and that (2) ZODB is a bad place to start on Zope programming. By these two points, should I infer that learning how to write external methods in Python *is* a good place? Can you, or someone else on the list, give me a suitable homework assignment for a first Zope programming project? I was toying with the idea of writing a checkbook register in Zope, but I think it might be beyond my capacities right now. Thanks again, Rick -- Richard P.
