All you have to do to maintain a session is start it before you call any variables. Once you've started the session, you can store variables for use in later scripts.
Beware though, once the user closes the browser, the sessions' over.
I'd use the following
SCRIPT 1:
<?php
// Start session
session_start();
// Set some variables (this simulates form input)
$_SESSION['answers']['Q1'] = 18;
$_SESSION['answers']['Q2'] = 36;
$_SESSION['answers']['Q4'] = "Fred";
?>
=============================
Hope that helps...
