Rather than using isset() you may need to use session_is_registered(). This is specifically for checking the existence of a session variable. I would do something like
<?php
// need this on all pages where you want to work with
// the session var
session_start();
// Check for the existence of the session var and create
// it if it doesn't exist
if (!session_is_registered("ses_username")) {
session_register("ses_username");
}
// Are we getting a form var thru ? if so pop it into the session var
if (isset($frm_username)) {
$ses_username = $frm_username;
}
// then in your scripts you can do
do_my_amazing_function($ses_username);
?>
As long as you have session_start() at the beginning of each script, $ses_username is now available across scripts.

Hope that helps.
