hi, i have set up plone & zope in linux. All these days i have used formulator + DTML(to design forms )& dtml alks 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 Prasad
