Hi Cetin,

Thanks...overnight I got thinking that it would work just as well to have one view for each child table and then another for the parent....a bit more work but simpler anyhow. Also, when I looked at the result set created by the multi-table view (i.e. a browse), I am sure the next guy in here would say "what the hey..." when they saw it!

Thanks for responding (thanks to Victor as well).

>>Anyhow, could not save the view to try it out. Should I be able to do this in the view designer or do I have to do a hand-coded view? or maybe I have to do 4 different views, one for each child table?
