Quantities for product and product options

Hi

I need help with setting up this product. There is a quantity for a product, and also for each product option. If I have four options, each of which has quantity 10 am I supposed to manually put 40 in the quantity for the product? Shouldn't the total quantity for the product be the automatic sum of the quantity of each item?

That's correct Steve!

Main quantity of product = total quantities of all options and you must manually entered main quantity and option quantity.

Sincerely, Giang
