[Zope] how to use the document object in a script

Wrestling with the ZopeBook (ScriptingZope.stx), I'm trying to call a script from a DTML document to return eq the title for the document (as learning curve). The document has: <form action="myScript" method="POST> <input type="submit"> </form> The 'myScript' has: Return context.title The result is the title for the folder where the document is in. I'm expecting the title for the document itself. Context always seems to be the folder I'm working on. How do I get the object (document)? Wim
