hi,
i have set up plone & zope in linux.
All these days i have used formulator + DTML(to design forms )& dtml talks to openflow & that works fine.
As i was not able to make dtml call zpt( as my dtml is currently talking to openflow--didn't want to change the sequence), i had to go with zpt talking to openflow.
is that possible , plz help me, how do i do this.
Below mentioned is what i have done.
this is my macros in zpt.here this form action points to dtml script.
-----------------------------------------------------------------
<tr tal:define="startdate request/startdate|nothing">
   <th align="left">
    <font size=5><font face="verdana"><b>
     Start Date:
    </b></font></font>
   </th>
   <td><input type="text" name="startdate"
       tal:replace="structure python:form.startdate.render(startdate)" />
   </td>
 </tr>
-----------------------------------------------------------------

this is my dtml script(talks to openflow) that tries to call zpt
----------------------------------------------------------
<dtml-var standard_html_header>
<h2><dtml-var document_title></h2>
<p> 
<dtml-let instance="workflow.addInstance('request',
   AUTHENTICATED_USER.getUserName(),
  'no comment',
  'Request for Grant by ' +  AUTHENTICATED_USER.getUserName(),
   activation=0)" instobj="_.getattr(workflow,instance)">
<dtml-call "instobj.manage_addProperty('startdate', startdate, 'string')">
<dtml-call "workflow.startInstance(instance)">
</dtml-let>
</p>
<p>
<a href="index_html">To frontpage</a>
</p>
<dtml-var standard_html_footer>
------------------------------------------------------------------------
it always gives an error like 
Error Type 
NameError
Error Value 
name 'startdate' is not defined

what is the problem
Thanks
