I have several hundred electronic documents that are set up as Resources. About a hundred of these are also available as printed documents and the users are able to order these via a shoping cart.

I want to be able to display a list of only those documents that are available as printed items i.e. a list of Resources that are "marked as Product".

If i use the product.list webpart it displays all other resources as well as the ones that are marked as products. I've tried filtering this but so far with no success.

Can anyone help?
