Hi Brad,
I have the same problem on that page. Our code for the Add to Cart button there is complete, but for some reason every time I click on it the entire page reloads from scratch and nothing is entered into the cart. I believe some other element on your page is interfering with the Add to Cart button, but I am not sure what is causing the problem specifically.
I'd recommend trying it without a View Cart button on the page to see if the cart opens in a pop-up window, and I'd also recommend trying to move the button to a different spot on that page or removing some of the other settings there to isolate what might be causing the page to reload when the button is clicked.
