So, if this is the result of a form submission how are you getting the POST
variables?
How/where is $industry being set? I appears that you are assuming that
variables are 'maintained' within a script, they are not. You have to
remember that although you are running the same script it is not the same
'instance' of the script as a request/response has occurred. You MUST pass
and retrieve SESSION/POST/GET variables if you intend to use them in your
script.
$_SESSION['x'] = $_POST['x'];
$_SESSION['y'] = $_POST['y'];
etc etc...

You do not appear to have set the SESSION variables before redirecting to
the next page.

Sorry, I cannot see where $industry is being set. This may just need
$industry = $_SESSION['industry'];
