Php Header() Function Error by onydchic(op): 12:27pm On Jul 14, 2006

Hey i need help with this, anyone good with php should let me know:
I'm trying to use the header() function to pull a certain variable from the previous page to use in the next one. here's the code
if (!$_GET[topic_id] ){ header(location: prevpage.php);
exit;
}
instead i'm gettin 'cannot modify headers, header already sent' error. i've used it b4, so i'm stomped. any ideas?
