$_SESSION data not storing

[insaynewrapper]

I'm having problems with $_SESSION data not storing
Case in point:
http://dfgray.pcriot.com/personal/blah1.php - this page writes to session
http://dfgray.pcriot.com/personal/blah2.php - this page reads the session
You can verify the source with these pages
http://dfgray.pcriot.com/source.php?f=personal/blah1.php
http://dfgray.pcriot.com/source.php?f=personal/blah2.php

session_start();
sorry

I'm so used to developing on my local server I forget it's not set-up the same as yours.
