Hello Ramesh,

Did you ever get this working? I am following this thread right now- because I need to modify the cart to only show one of each product- my store is all used and rare books- and I only have one for each inventory number.
 
I don't want the customers typing in a quantity of "2" when checking out, because each book is unique and there is only one available.

Any help appreciated. I am working on the code suggestions from the beginning of this thread, but have not gotten it to work.

Thanks,
Catherine
