Read the DTML Reference (search for expressions or the "expr" tag). It's at http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.html Here's an example: <dtml-call "REQUEST.set('var1',0)"> <dtml-call "REQUEST.set('var2',1)"> <dtml if "var1 != var2"> <dtml-var var1> is not equal to <dtml-var var2> </dtml-if> Setting variables for use in DTML in the REQUEST namespace is a convention. You can compare almost any two objects this way, though (such as the field result of a SQL method to the title_or_id of a Zope object). Note that writing <dmtl-call "REQUEST.set('var1',0)"> is equivalent to <dtml-call expr="REQUEST.set('var1',0)">. The former is shorthand for the latter.

does anyone know where i can find documentation of how to compare to vars?
for example: dtml-var a=1 dtml-var b=0
i need to know that b is less than a.
thanks, kyle
