Sorry if this is an inappropriate post, but I am desperate to get this mod working correctly.

I am looking to hire someone who is confident in being able to correct this mod on my site.

There seems to be a lot of things wrong. The save button doesn't work when loading the quantity in admin(this is the less important issue)

The big issue is it allows checkout of items no matter the stock status. Also once the item is in the cart it only shows the parent product name it does not show the attribute name.
Please PM me if this is something you think you can fix.
