// Options pricing script by Erik Daniel http://landmine-design.com
//Created: Oct7th, 2008
//Version 1

// This script gets the pricing for a configurable product from the option SKU based on the other option
// chosen by the user
// It also forces the user to choose option from top to bottom
// and resets the price if the user changes option after the price has been set
