Simon, I admit that I struggle often with the terseness of your prose. Is this #4 your statement of the problem that I ran into, as per my original post? In other words, is Where { X p _y . _y p Z . } using the value in a second query? If not, does one of your other points address this? thx, kc -- Karen Coyle [log in to unmask] http://kcoyle.net m: 1-510-435-8234 skype: kcoylenet
