You have to call session_start() on every page with which you want to access the session. session_start() must be called before you try to access any of the variables or objects stored in that session. HTH.

following is the script used.

<?php
session_start();
if (!$userid)
session_register("userid");
else
echo $userid;
if ($submit)
{

$db=mysql_connect("localhost");
mysql_select_db("mysql",$db);
$result = mysql_query( "Select uid from userlist where uid ='$uname' and password='$upwd'",$db);
if ($myrow=mysql_fetch_row($result))
 {
//$HTTP_SESSION_VARS["userid"]=$uname;
 $userid = $uname;

//  header("Location: http://$HTTP_HOST/rightfrm.php");
}
else
echo 'invalid User or Password';

}
?>

make sure that the PHPSESSID is sent to all pages either through a cookie or the URL.
