[Zope] traversal problem

[john blair]

I tried this
<p tal:define="category_id
request/form/category;category python:getattr(here,
category_id);"> </p>
  <table>
    <tr tal:repeat="item category/objectValues"> 
          <td tal:content="item/id">Id</td>
          <td tal:content="item/title">Title</td>
    </tr>

    </table> 

It still gives

Error Type: KeyError
Error Value: 'category'
