That was the problem, thank you very much for your help!  :)

Hey guys, I have created a page which had the PHP as listed below and the page works fine however if the user clicks refresh the pages goes all white and blank. I was just wondering why it does this? Thanks [code] <?php session_start(); include ('db.php'); $link_id = db_connect(''); $g = "SELECT ff, nn e FROM cu WHERE Id = '". $HTTP_SESSION_VARS ["Id"]."'"; $rs = mysql_query($g, $link_id); if (mysql_num_rows($rs) > 0 ) { $r = mysql_fetch_assoc($rs); $HTTP_SESSION_VARS ["Id"] = $r["Id"]; } else { echo $HTTP_SESSION_VARS ["Id"]; exit(); } ?> [/code]

OOps that was my bad sorry it was a fault with the connection, sorry about that and thanks for your help.
