header already been send...

[Dondxon]

hey!

im using a login session on my page which is not on the forums. and to do that i have to require this:

PHP Code:

 <?php
chdir('./vb');
require_once('./global.php');?>

but if i do that it Unable to add cookies, header already sent on line 2. because i always put that code on top of the page.

where do i have to put that code to prevent that message?

if you can help i would really appreciate it. a whole community is waiting for it!
