Determining unit price from a pricing matrix...

I'm trying to build a calculator for product pricing. The idea is that a person would select a number of criteria and the calculator would generate a unit price which would then be multiplied by a quantity to yield an order price.

However, I can't figure out how to use the input criteria to lookup the unit price from a pricing matrix. The logic formulas seem to assume TRUE or FALSE, which doesn't allow for more than two possible anwers. And the LOOKUP formulas don't seem to account for multiple criteria.

I've attached a simplified example as a screen shot. Does anyone know how I can determine the unit price, based upon the answers of two different criteria?
