DOH! *laugh* Of course, what I proposed wouldn't work, because IBO still
wouldn't know what the key was... I jumped on the NULL vs something non-null
idea and didn't think it all the way through. However, apparently my
misguided suggestion got the wheels of ingenuity rolling for you, which was
my real intention in the first place. @;-O)
