I have the attributes contribution installed in my OScommerce store but the price differences and the amounts aren't showing in the shopping cart, visit [url removed, login to view] and click on one of the seed products on the front page to test and see what is happening.
This shouldn't be a big deal to fix, if you can do it for $15-18 that would be ideal, if not, name your price and if i am able to afford it I'll pay.
Payment can be in escrow if you'd like or full amount after completion. I do have several other needs in my store and another one that I manage if you are available for other work.
the store is built in OsCommerce MS2 2.2
the attributes contribution is the Product Attributes - "Option Type Feature v1.7.2"
