[Zope] Funny problem with DTML, please help!

[pan@aster.net]

I managed to get it to work.  It seems that the variable first
mentioned in

<!--#call "REQUEST.set('count_yes', 0)"-->

gives an error when used in:

     <!--#if "answer == 'Y'"-->
       <!--#call "REQUEST.set('count_yes', REQUEST['count_yes']+cnt)"-->
     <!--#/if-->

and not in

     <!--#if "answer == 'Y'"-->
       <!--#call "REQUEST.set('count_yes', cnt)"-->
     <!--#/if-->

The rest of the variables can be incremented without problems.  This
is really strange?!

I have it now working as:

<!--#comment-->
Calculate the vote percentage
<!--#/comment->

<!--#call "REQUEST.set('count_dummy', 0)"-->
<!--#call "REQUEST.set('count_yes', 0)"-->
<!--#call "REQUEST.set('count_no', 0)"-->
<!--#call "REQUEST.set('count_all', 0)"-->

<!--#in sql_distinct_votes-->
  <!--#if "cnt == 1"-->
    <!--#if "answer == 'Y'"-->
      <!--#call "REQUEST.set('count_yes', REQUEST['count_yes']+cnt)"-->
    <!--#/if-->
    <!--#if "answer == 'N'"-->
      <!--#call "REQUEST.set('count_no', REQUEST['count_no']+cnt)"-->
    <!--#/if-->
    <!--#call "REQUEST.set('count_all', REQUEST['count_all']+cnt)"-->
  <!--#/if-->
<!--#/in-->

<!--#comment-->
Now display the results
<!--#/comment-->

<h2> Total : <!--#var "REQUEST['count_all']"--> votes</h2>

<ul> 
  <li>Yes : <!--#var "REQUEST['count_yes']"--> votes (<!--#var "_.round(((REQUEST['count_yes']+0.0)/REQUEST['count_all'])*100,1)"-->%)</li>
  <li>No : <!--#var "REQUEST['count_no']"--> votes (<!--#var "_.round(((REQUEST['count_no']+0.0)/REQUEST['count_all'])*100,1)"-->%)</li>
</ul>
