[Zope] Newbie: Date checking?

[Andy Gates]

A quicky for you Zopistas:  I have some dates in a database, which 
govern when a story becomes live and when it expires.  I need to do a 
test along the lines of:

dtml-in stories
  if (startdate is past) and (expirydate is future)
    show the story
  /if
/in

I have seen the fmt parameters isPast and isFuture and this gives me a 
true/false response:  <dtml-var startdate fmt=isPast>  but how do I use
that in an if test?  I keep (as usual) getting syntax errors.  Help!
