Dear PtoP:

The Professional PHP Programming book has a section case study 1 on building a shopping 
cart application. I have found that neither the code from the book or the downloaded code will 
work on the changing quantities part on page 590-592 of the book. My quantites do not 
change when I enter them to on display.php. Please let me know if there is another way to 
make it work or what I may be doing wrong to make the code not work.

Thanks;
