Session Variables - Error

Dear List - Thanks for your help. Here is another one..... I cannot get my session variables to work. The program will print out a chess board and show the positions of the pieces after the move Here are code snippets: The program is chess2.php <?php session_start(); error_reporting(1); if (!isset($_SESSION['results'])){ //this always returns as not set. print_r($_SESSION); echo "starting"; $results = array(array("Br", "Bn", "Bb", "Bq", "Bk", "Bb", "Bn", "Br"),array("Bp", "Bp", "Bp", "Bp", "Bp", "Bp", "Bp", "Bp"),

                        array("", "", "", "", "", "", "", ""),array("", "", "", "", "", "", "", ""),array("", "", "", "", "", "", "", ""),
                        array("", "", "", "", "", "", "", ""),array("Wp", "Wp", "Wp", "Wp", "Wp", "Wp", "Wp", "Wp"),
                        array("Wr", "Wn", "Wb", "Wq", "Wk", "Wb", "Wn", "Wr"));

$_SESSION['results'] = $results; print_r($_SESSION); } else {

         $results = $_SESSION['results'];
         echo "<br />starting values<br />";
         print_r($results);
