It's always something obvious. I was not checking the session variable's value
at the correct point in the script, hence the display was not being altered by
its results. I've managed to get my code to display properly now, but I can't
retain state between queries.
My reason for using session variables was to ensure that a user's viewing
selection (with or without details) was retained. However, when I reload the
page with a new URL query string (for a different catalogue section), the view
settings revert to no details. This also occurs when reloading the page with
the same query string. Again, I'm sure it's something obvious but I just can't
seem to figure it out. What stupid mistake am I making this time? Thanks
again.

100%. I went so far as to move session_start() before every other element on
the page, even removing it from my include file and directly inserting it into
the actual page.

Mike answered that part quite nicely. I just realized that I had
register_globals = On, but that is now changed and I still have the same result.

Subject: RE: setting session variables via a form
Edward,
Are you certain that you have issued the session_start() call at the
beginning of the page? According to the session stuff on PHP.NET, you need
to make sure you have session_start() at the top of the page before you do
anything else with the session. For example, I have on one of my simpler
pages:
session_start();
session_register("isRegistering");
$_SESSION["isRegistering"] = "true";
header("Location: http://mywebsite.php";); /* Redirect browser */
Furthermore, your register_globals setting will have some impact on your
syntax.
See http://us3.php.net/manual/en/ref.session.php
Hope that helped.
