To get this example working:

1] Have Dojo on the server. (Please read through the inital chapters to know more about dojo and using it.)
2] The files shopping_cart.html, logout.html and Test.php are assumed to be in same directory. If you don't plan to do so, you need to modify the URLs in those html  files.
3] Make sure that relative URLs (in 'shopping_cart.html') to 'dojo.js' and 'tundra.css' are pointing to correct location.
4] You require PHP installed to run the Test.php script.
