SESSION VARIABLES

Hi All, I've created 3 sample scripts, pls see below. My problem is that page3.php can't display the value $username and $password Or is it because it the variables were not importe to that page, that's why $username and $password has no value? If it is, how can I import it? Thank you --------- login.php ------------- <html> <body> <form method="POST" action="auth.php"> <p> USERNAME: <input type="text" name="uname" size="20"></p> <p>PASSWORD: <input type="password" name="passwd" size="20"></p> <p><input type="submit" value="Login" name="login"></p> </form> </body> </html> ---------- auth.php ------------- <?php $username = $_POST[uname]; $password = $_POST[passwd]; session_start(); if ($username == "ronald" AND $password == "ronald") { session_register("username"); session_register("password"); echo"<html> <head> <script language=\"javascript\"> function bukas() { window.open(\"page3.php\",\"_new\"); }; </script> </head> <body onload=\"bukas();\"> <p>$username </body> </html>"; } else { echo "INVALID, TRY AGAIN"; }; ?> --------------- page3.php -------------------------- <?php echo "$username"; echo "#password"; ?>
