variables set by dtml-let are only in the namespace in between the dtml-let
tags.  When you close the tag, the variables are removed.  If you can't use
dtml-let tags, you can push the variable into REQUEST with:

(not tested) 

<dtml-call "REQUEST.set('revision','%')">

Subject: [Zope] How do reset a dtml-var 

Hi, 

I am trying to check to see if the dtml-var revision is set to a null and if

it is I want to set it to "%" as a sql wildcard. This is my test. 

<dtml-if expr="revision==''"> 
<p><dtml-var revision>test if1</p> 
<dtml-let revision="'%'"> 
<p><dtml-var revision>test if2</p> 
</dtml-let> 
<p><dtml-var revision>test if3</p> 
</dtml-if> 

Here are my results. 
test if1 
%test if2 
test if3 

How come the variable is not set after I leave dtml-let statement? Thanks.
