[Zope] Zope products and DTML

It's me again - and still having problems. I have a Zope product. It generates a load of useful information, but I wish to insert some DTML tags into the data that is output. I have no problem inserting these tags, but they will not render. Please could someone please explain how to encourage DTML to be parsed from the returned text. Thanks in hope and anticipation Stephen ----------------------------------------- Dr Stephen Rudd - genome astronomer Bioinformatics group Turku Centre for Biotechnology Tel. +358 2 333 8611 Fax. +358 2 333 8000 ------------------------------------------
