I've tracked the code of quantity selection and looks like quantity depends from a number of products in stock. So please look into that since most of Your products (if not all) has a 0 set in stock. Anyway template comes with quantity, but it's up to VM to enable it, so You need to talk to VM support or check VM documentation to learn what actually needs to be done to enable it. Because I can see a variable "vm3_show_quantity", inside the code, but there is no such thing in VM configuration.
