This is obviously a very basic question. But I am missing something :)

I am having a lot of trouble finding where I can input the amount of a certain item that I have in stock.

If I try to edit my product, I guess I don't really understand the boxes
Product Qty Minimum:
Product Qty Maximum: 0 = Unlimited, 1 = No Qty Boxes
Product Qty Units:
Product Qty Min/Unit Mix:

It seems that no matter what numbers I put in there, when I go to my list of products, the quantity of each item reads "0".

Thanks for any advice!
