I have a modded version of oscommerce (oscmax, latest version), and the products i sell use multiple attributes. There was an error with the [url removed, login to view] file where the item wouldnt be subtracted from the inventory after the item was purchased. I tried fixing the problem, but the farthest i could get was getting the program to subtract stock from non attributed items (no sizes, type, or any other option, just a product listing with a buy now). The code error more than likely is in this file and not another. It shouldnt be much of a problem for someone familiar with oscommerce, i just do not have the knowledge nor the time to deal with it.
I can do this oscommerce fix just like others , pls check my feedbacks. I am available right now.. waiting fo ryou .. availabe to msn chat upon selection.
