[Zope] dtml problem

Hi! I have a problem with dtml and the docs won't help me out: i want to call e.g. manage_edit on a dtml document. the document's id is stored in the variable doc_id (e.g.). how do i call the function? <dtml-call "_['doc_id'].manage_edit(_['doc_src'], _['doc_title'])"> doesn't work, as zope treats _['doc_id'] as a string and complains that it can't call manage_edit on a string. what's the correct code? thanks in advance! regards, Klaus -- Klaus Herrmann <klaus.herrmann@goelz.com> Goelz & Schwarz GmbH, Munich www.goelz.com phone:+49 - (0)89 - 544 67 0 22 fax: +49 - (0)89 - 544 67 0 10
