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 __________________________________ Celebrate Yahoo!'s 10th Birthday!
