Learn about the difference between the "name" attribute
and the "expr" attribute.

Maybe

  <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>

would make a good reading?

In short:

   '<dtml-in XXX>' is equivalent to '<dtml-in name="XXX">'
   In this case "XXX" is not interpreted as a function
   call, even when it may look like one.

   You want '<dtml-in expr="XXX">' which can also be written
   as '<dtml-in "XXX">' In this case, "XXX" is interpreted
   not as a name but as a Python expression.

   The same applied not only to "dtml-in" but to almost
   all DTML commands.
