I have just been appointed as maintainer for a ZenCart configured by one of our summer interns, and honestly, I've got no idea what I'm doing with it. Yesterday I was tasked with adding birthdate validation onto some of the products, and that was easy enough. However, apparently a feature that was coded by the intern has utterly vanished, and it wasn't due to my code (I've disabled all my code to verify this).

ZenCart Version: 1.3.8a
Site: https://store.goremountain.com

The problem I am running into is that the Add To Cart buttons on the product category (such as this one: https://store.goremountain.com/index...=index&cPath=1) displays allow bypassing of required attributes on products.

What should happen when the Add To Cart button is pressed is it should take the user to the product page with multiple instances of the form fields depending on the quantity of the item requested.

Apparently this was working when our intern left, but has since stopped working. I've got no idea how to get it working again, nor can I find code to indicate that it ever worked to begin with.
