[Zope] traversal problem

[john blair]

Hi I have say 3 folders with following ids
folder1
folder2
folder3

Now I show this list to the user in a comno box. User
selects folder which results in displaying of the
contents of that folder.
Say the select box name is category
i.e <select name="category">
now when the user selects one of the category what I
do is
<p tal:define="category request/form/category"> </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 gives me a key error .What should I do to correctly
traverse the folder
