Thanks John and others.
I'm using the script and no values show up in the page:
session_bb.php
after I submit the values in the <select> form.
If somebody would like to test both scripts (session_aa.php and
session_bb.php) and get back to me I would be grateful.
As I said, these were from her book/CD.
Thank you.
