Ahhh... do you mean something like, if the customer enters "x" width into field A, and height "x" into field b, they get multiplied?
That's way above my head, and as far as I know, not something that can be done by default. As far as where they're stored... I think that they are stored in the database only when the order is complete, and before that, they are stored in the form of cookies? As I said, that is above my head.
I'm just guessing that multiplying the two is what you're trying to do... perhaps you can find some kind of "free" javascript calculator that you can insert into the page so the customer can use that to figure out the number, or you can instruct your customers to multiply themselves width x height, and have them enter the value into a text field instead.
