Recalculating Totals Using Attributes
I'm in need of some assistance. I recently built a product model that calculates the hours and price of software training using mulitple attributes as input fields and a resource to store the values. The resource then updates the number of hours on the software training product and the training hours attribute pulls in the price from an attribute adjustment table. Evreything works well when the user is doing the initial customization. The problem I'm experiencing is if the user goe back and updates the input attributes, the software training hours and price doesn't get recalculated.
I read somewhere in Bookshelf that you are not allowed to update an attribute value once it has been set (I'm paraphrasing of course). Is there a way get the product model to behave like MS Excel, in that when a user re-customizes and updates the attribute values it will recalculate the totals, update the resource and change the price?
