[Zope] catalog.getpath -->search results as links

I am trying to follow along with the zcatalog tutorial, but when I get to the instructions where you can make your zope object results links to the actual object the following instructions are used: In the source of report, find the following line:: <tr><!--#var title--></tr> Replace it with this: <tr> <a href="<!--#var "catalog.getpath(data_record_id_)"-->"> <!--#var title--> </a> </tr> In making this change however, my search results gets broken with the following error: Error Type: NameError Error Value: catalog Any ideas why? Has the syntax changed? My exact replacement is: <a href="<!--#var "catalog.getpath(data_record_id_)"-->"> <!--#var title--> </a>
