How to have quantity options for different sizes of items in the payment form

Hey guys! So I am now offering T-shirts and backpacks for sale. I was wondering how to get the form to have the option of 2 quantities of the same size shirt. I just had the thought of adding all the sizes, but I am just curious if the customers would be able to get two of the same size if they wanted to. 

You can enable the Quantity option on the items/products on your payment form.

Review this user guide: How-to-Add-Options-to-Payment-Forms

When done correctly, each itesm/products will now have Quantity options.

Hope this help. Let us know if you need further assistance.
