OK, that helps a LOT, Rik!
By "vews set" I meant something totally irrelevant; I thought a "set"
would be, for instance, a 'set' of variables contained in
$_SESSION['views']=1 , then another, different set would be contained in
... =2, and so on. I kind of caught on some when I came across a PHP
page counter but ... .
%_SESSION is the piece I've been missing out on; don't recall coming
across it before, but that doesn't mean much. I'm still learning to
find my way around the w3schools heriarchies.
Thanks much!
