Header problems

[Anon]

Hi... I am having problems with headers and it always output this message:

Warning: Cannot add header information - headers already sent by (output started at /home/virtual/site76/fst/var/www/html/motor/trial.php:10) in /home/virtual/site76/fst/var/www/html/motor/trial.php on line 10

Below is the whole code that I am trying to use... Thanks!!!!

<?
require_once(\"./inc_conf.php\");
session_start();
session_is_registered(\"trading\");
session_is_registered(\"number\");
list ($tradein_price) = $trading;
list ($idnum) = $number;
?>

<? header (\"Location: http://www.synergyasia.net/motor/show.php?idnum=$idnum\"); ?>
hello... this is your price for today...

Here:

?>

Don't leave a line! Because that line is outputted to the browser, and therefore your headers won't get thru. Just do:

<?
require_once(\"./inc_conf.php\");
session_start();
session_is_registered(\"trading\");
session_is_registered(\"number\");
list ($tradein_price) = $trading;
list ($idnum) = $number;
header (\"Location: http://www.synergyasia.net/motor/show.php?idnum=$idnum\"); ?>
