Hi,

I've been trying for a while now to figure out how the pricing of attributes work and also in which files the pricing are dealt with.

I thought i found it in the file functions_prices.php but it looks like this file is only used for displaying the attribute prices and not actually calculating anything that got added to the shopping cart.

Basically what i need to do is have products with 2 attributes and have the final price be multiplication of the option values between attributes.

To be as clear as possible what i need it:

Product 1 (priced by attributes)

Option1 (customer can select one or more of those):
Small: 1
Medium: 4
Big: 3

The 1,4,3 at the end are values used to compute the final price. Could be any values

Option2 (Customer can only select one of those):
Original: 25
Tempered: 75
Customized: 85

Final price for product 1 should be

(SUM of Selected Option1) * Selected Option2

If the customer selects Small and Big Tempered the final price would be (1+3)*75 = $300

Anyone would have a clue how to do that? and which files need to be changed to achieve this?

Thanks
