By now I realized that the units are located at
http://www.sams.rs/new2/administrator/index.php?option=com_jshopping&controller=units
I do not understand why you removed the button. And also they are no longer related to the product.
Is there a possibility that instead of word "pieces" in frontend be replaced with a unit that refers to a product?
I'm looking for this option for my small shop for cables that are sold by meter.
