If I create a folder 'test' under my root folder, in which I make a new 'CD' object called myCD (as described in the Z Classes tutorial), and then create run this bit of DTML in that folder: <!--#call "myCD.manage_changeProperties({ 'title' : 'Rivers', 'artist' : 'Daniel Drucker', 'description' : 'a piece of dog' })"--> Instead of myCD's title being changed, the containing folder 'test' gets its title changed to 'Rivers'. What am I doing wrong here? Daniel Drucker
