Hi Bob,
        Thank you for your reply and for taking the time to test that code.  
I went to your site (http://circlecity.co.uk/testarea/test.php) and everything 
works perfectly but on mine it doesn't  When I click on the "Test" button, 
the SID changes and the session variable goes blank.
       I only have the briefest information on "strip_tags( )".  From "PHP 
and MYSQL Web Development" I have: "This function prevents users from planting 
malicious scripts in user data that you might echo back to the browser."  Where 
would you normally insert it?  Can you suggest where I can find more 
information on this function?

Thanks again.......Bill
