I'm a relative beginner to Zope, so I'm not sure what I'm talking about <grin>, but it seems to me from my limited experience that you can't call out an object using a URL in a dtml-var. Instead you need an object reference. So try something along these lines (this is untested because I'm in the middle of my own debugging mess): <dtml-in products> <dtml-var "Products.get_item(_['sequence-item'],0).New" </dtml-in> I'm sure the above is not right from a Zope standpoint, and the Python is probably wrong too, but maybe it will send you in in the right direction. What I'm aming for with that psuedo code is to get the property of Products whose name is in sequence-item, without rendering it (that's the ',0' bit), and to pick up *its* 'New' property and render that. Maybe a real Zope expert can correct my code. Or more likely, as others have suggested, using a ZClass is the right direction anyway, which would avoid the whole syntax issue <grin>. --RDM
