Endnu et session problem - tror jeg.

Får denne fejl:

Warning: Cannot modify header information - headers already sent by (output started at c:\apache\htdocs\techcity\beta\checkuser.php:13) in c:\apache\htdocs\techcity\beta\checkuser.php on line 63

Linie 13 står der: <? include("inc/header_inc.php"); ?>

Linie 63 står der: header("Location: login_success.php");

Hvad er det lige problemet er her?
