Thank you for the comments on conditional replacements. I now have another oddity to deal with. When adding products to the session cart I am not able to have the count incremented if the product has already been selected, rather another item is added to the cart. I copied the code from the book as carefully as I could and could find no error but to be sure I then cut and pasted the code
