How to make php script see session vars?

How to make that my php script see session variables?

I made script like this(index.php):

<?php
session_start();
session_register('var55');
$var55=123;
.
.
.
?>

And on this php page (index.php) is a link to another php page (index1.php), and on that page variable $var55 is not set.
I have site with few php pages and I want that visitor on the first page enter his username and password and that I can use those variables on any php page in my site without passing variables in address bar.
please help
Thanks

Hi
I've asked loads of session questions recently and have got some good help.
Let me try to help someone else!

You must put session_start() at he top of every page you wish to access your session vars.

Also be careful if you are using forms and you want the user to be able to go back and enter new values for the same vars.
It tends to get confused and the original var is the only one it recognizes!

You can solve the problem like this.
<?
page 1
session_start();
session_register("var");
// USER PUTS IN NAME
?>

<?
page 2
session_start();
$ses_var=$var
?>

You can then access $sesvar on any page!
