Problem with Header()

Thanks to all of those who have helped so far, I get still get this error: Warning: 0 is not a MySQL result index in (absolute path)/html.php3 on line 17 Whenever someone accesses html.php3 alone, and not with html.php3?id=# All I want it to do is to check if it's empty and then redirect. Here is my code: <html> <? $server="localhost"; $username="username"; $password="pass"; $database="database"; $table="table"; @mysql_connect($server, $username, $password) or die("Connection"); @mysql_select_db($database) or die("Database"); ?> <? $Result=@mysql_query("SELECT * FROM $table WHERE id=$id"); while($row = @mysql_fetch_array($Result)) if ($id) { header("Location: http://www.domain.com/"); exit; } else { $title = $row["title"]; echo "<head> <title>$title</title> <meta http-equiv='Content-Type' content='text/html; charset=iso-8859-1'> <style type='text/css'> <!-- FORM { margin: 0px 0px} --> </style> </head>"; } ?> Thanks again, Jay Stauffer
