Add quantity of available products

Thank you so much! Is there a way to chose to add qty of inventory available to purchase that I have available daily along with preordering? What would you suggest the best way to set that up. If you could look at my form and help me come up with a way to allow customers to order what I have left available and once I’m sold out it can do to preorders/or would I have to set up two separate forms? Thank you so much for your assistance!

What you want can be done using regular fields instead of your current Purchase Order field.
