I'm having an issue with products priced by attributes. I set up a test product, which is priced by the number of units a customer wants to purchase to allow quantity discounts -- i.e.:

10 units - $21.00
15 units - $31.50
20 units - $42.00

and so on. The base price for the product is $0, and I removed the "+" from the price when I assigned the attributes to the product.

Everything displays correctly, but when I chooes any attribute and add the product to the cart, it shows $21.00, instead of the price assigned to the selected attribute. The cart lists the correct choice -- i.e., 20 units -- but instead of showing a total of $42.00, it's showing $21.00.

I've switched back to the classic theme and still have the same problem. I removed all of the attributes and started over again and I'm still getting the same results. I'm not sure if I'm screwing something up?

The only plug-ins I've installed is "pretty professional breadcrumbs" and "blank sideboxes," if that matters.
