Need help with shopping cart

I have a dropdownbox where people can first select a catagory.

According to the category chosen, a datatable gets filled out with a CachedRowSet containing the items in that category.

Each row has an inputtext and a submit button

People can fill in the quantity they want to order.

My question is how/where can I save those quantities

I also want those quantities redisplayed in the inpuxboxes even when users switch to another category and return back..

Redisplaying doesn't seem to be a problem as long as I don't change category (which is obvious since the datasource of the datatable changes)

Does anyone has an idea on how to save those values and redisplay them
