PHP sessions not saving from page to page

Question

i'm having some issues with PHP sessions. I'm pretty new to PHP so my apologies if i'm being completely stupid.

I have a login.php file that once the user name and password has been checked etc it has the following code:

if($pass === $row2['PSWD']){
    session_start();
    $_SESSION['test']="hello";
    mysql_close($con);
    header("Location: page.php");
}else{
    die('Wrong password');
}

then on page.php I have the following at the very top, about the tag:

<?php
session_start();
session_register(); //just in case...(should not be needed)
echo "Result:".$_SESSION['test'];
?>

And all I get at the top of the page is "Result:"

Any ideas? As from everything i've been reading it should be as simple as this?

Thanks in advance!

EDIT:

My error logs are showing:

Answer 1

You need to put exit(); after your header redirection, otherwise you have just loaded two pages of content into 1 page.

Answer 2

after header location give exit();
