Products Say Out Of Stock and Unavailable to order.

EDIT: I HAVE RESOLVED THE PROBLEM. IT HAD TO DO WITH MISSING PRICES FOR THE VARIATION CAUSING IT TO SAY UNVAILABLE FOR ORDER.

I am using Generate Press templates with Wordpress. I have added in a product and set the product quantity to 1000. However, when I click on it, it says "This product is currently out of stock and unavailable."
