Thanks, I'll rephrase it using my real life problem: I have a Picture class, which comprises image, title, description, etc. I also have a ProductItem class, which subclasses Picture to include a price, etc. So finally I have got a ProductItem class, which has a title, image, price, ... I can access properties inherited from the Picture no problem. The problem is that the default management screen for editing the properties of ProductItem, propertysheets/Details/manage, only provides a means of editing the unique properties of ProductItem. Is there a means of managing all the properties of a ZClass, including those of its parent class? Or do I have to code my own management screen to do this? And if so, what is the correct way of refering to these properties in DTML? Feeling a bit dumb...cheers, Seb
