Evening all...

I am trying to set a session variable and redirect.

If I link to language.php without the get variable in the URL the redirect works...otherwise I get a 404 and I don't know why

PHP Code:
$_SESSION['language_code'] = $_GET['language_code'];

header'Location: http://www.spanishpropertymagazine.com/index.php' ) ; 
spanishpropertymagazine.com/language.php?language_code=ES does't seem to work

Halp me pleaz...
