If you look at the source of the document, you will see it is returning
something - a reference to a function object. Its just that it
is in angle brackets so your browser thinks it is a HTML tag.

The example should read <!--#var "PARENTS[0].title_and_id()"-->, which
actually calls the title_and_id method

<dtml-with "PARENTS[3]">
    <dtml-var id>
</dtml-with>

Or if you know the id of the News folder ('News'?), then you can try:

<dtml-with News>
    <dtml-var id>
</dtml-with>

This example finds the object with id 'News' via aquisition (so it can be
any number of folders up, provided there are no other objects in the aquisition
path with the same id).
