Our product is actually provided from a manufacturer, allowing there to be an unlimited quantity. But, if I leave the "Quantity" section in the "Data" area of a product blank people can not purchase the product. Is there a way to make the system recognize an "unlimited" product quantity?
Please go to EShop->System->Configuration->Optionn tab, at Stock Checkout, please choose Yes. Then the system will allow customers to still checkout if the products they are ordering are not in stock.
