Thanks, putting session() right at the top fixed this. Thanks for the hints

I'd describe myself as a "basic" php programmer.... I'm trying to build my first multi-page forms. The first page is calculator_q1.php No session variables are needed here, I have omitted a few options, the code looks like this <form id="page1" method="post" action="calculator_q2.php"> <h1>1. Which best describes the primary and secondary sports combination that will be played on your pitch?</h1> <table> <tr><td>Rugby only</td><td><input type="radio" name="1_primary_secondary_combo" value="Rugby only"></td></tr> <tr><td>Rugby/Soccer</td><td><input type="radio" name="1_primary_secondary_combo" value="Rugby Soccer"></td></tr> <tr><td>Soccer/Hockey</td><td><input type="radio" name="1_primary_secondary_combo" value="Soccer Hockey"></td></tr> </table> <input class="blue" type="submit" value="Next"> </form> The 2nd page is calculator_q2.php. This has some php to start the session, copy the result of form 1 to a session var, I do a debug echo and the variable is printed correctly so I think have captured it correctly. In extract, I do this: <?php //Start the session session_start(); //Store our posted values in the session variables $_SESSION['1_primary_secondary_combo'] = $_POST['1_primary_secondary_combo']; ?> <?php $debug=True; if ($debug) { echo ("Debug: session for q1 = ".$_SESSION['1_primary_secondary_combo']); } ?> <form id="page2" method="post" action="calculator_q3.php"> <h1>2. Please choose a preferred surface</h1> <table> <tr><td>3G Rubber Crumb Filled Turf</td><td><input type="radio" name="2_preferred_surface" value="3G Rubber Crumb Filled Turf "></td></tr> <tr><td>Sand Filled Turf</td><td><input type="radio" name="2_preferred_surface" value="Sand Filled Turf"></td></tr> <tr><td>Sand Dressed Turf or<br>a Water Based Surface</td><td><input type="radio" name="2_preferred_surface" value="Sand Dressed Turf or a Water Based Surface"></td></tr> </table> <p> <script> function submitForm(action){ document.getElementById('page2').action = action; document.getElementById('page2').submit(); } </script> <input class="blue" type="button" onclick="submitForm('/calculator_q1.php')" value="Previous" /> <input class="blue" type="button" onclick="submitForm('/calculator_q3.php')" value="Next" /> </form> So far so good, but when I introduce page 3 (calculator_q3.php) then it prints the previous page's (from page 2) variable but can't find the session variable from question 1. This is from calculator_q3.php: <?php //Start the session session_start(); //Store our posted values in the session variables $_SESSION['2_preferred_surface'] = $_POST['2_preferred_surface']; ?> <?php $debug=True; if ($debug) { echo ("Debug: session for q1 = ".$_SESSION['1_primary_secondary_combo']); echo ("<br>Debug: session for q2 = ".$_SESSION['2_preferred_surface']); } ?> <form id="page3" method="post" action="calculator_q4.php"> <h1>3. Please choose one watering option</h1> <table> <tr><td>With a Rain Gun System</td><td><input type="radio" name="3_watering_option" value="With a Rain Gun System"></td></tr> <tr><td>With a Rain gun System + Water Borehole</td><td><input type="radio" name="3_watering_option" value="With a Rain gun System + Water Borehole"></td></tr> <tr><td>Not Required</td><td><input type="radio" name="3_watering_option" value="Not Required"></td></tr> </table> <p> <script> function submitForm(action){ document.getElementById('page3').action = action; document.getElementById('page3').submit(); } </script> <input class="blue" type="button" onclick="submitForm('/calculator_q2.php')" value="Previous" /> <input class="blue" type="button" onclick="submitForm('/calculator_q4.php')" value="Next" /> </form> To see this in action see: http://www.sports.hardingweb.net/calculator_q1.php Any insights would be appreciated. Many thanks.
