When you click a link, a new request is send to Zope.
This creates a new REQUEST object with no reference to the old
request at all. "date_code" from the former request is lost,
until you (as application developper) take steps to prevent this.

You options:

  *  use a session product (--> zope.org)

  *  use a cookie (--> Zope Online Help --> API reference --> RESPONSE)

  *  use a query string in your links

     <a href="dest?date_code=&dtml.url_quote_plus-date_code;">...</a>
