session variable problem

i have been having difficulty with session variables - i seem to be able to
set them, but when i wish to have another page update them, they remain as
they were. this makes them utterly useless to me.
does anyone know why i am having this problem and what i can do to rectify
it?

On each page you must call session_start()

Are you doing that?

yes, session_start() is called at the top of every page
perhaps i should try and be a little more clear:
the variables are set with no problems, and i can call them from other pages
where i declare session_start(). however, if i want those pages to update
the variable, the variable remains the way it was initially set.

for eg:

page1.php:

<?php
session_start();
$test = "hello";
$_SESSION["test"] = $test;
header("Location: page2.php");
?>

page2.php

<?php
session_start();
echo "original value: ".$_SESSION["test"]."<br />\n";
$_SESSION["test"] = "world";
echo "new value: ".$_SESSION["test"]."<br />\n";
?>

page2.php would output:
original value: hello
new value: hello

much to my chagrin.
please note - this code has NOT been tested. this is just stuff i knocked up
to show how much i know about performing this operation and the errors i
have been experiencing by utilising it in exactly this fashion. therefore,
if i am missing a semicolon or a bracket or suchlike from the above example,
this is not what is causing the problem.

any help would be greatly appreciated.

I clipboarded the code to the appropriate files and it works fine.

The output I get is:
original value: hello
new value: world

So your problem must be somewhere else.
