Button Not working on Landing Page

I successfully created my download and I think I set all the data (i.e. payment gateway info etc.) filled out properly. I watched all the movies on the site and thought I did everything right. I have all this displaying on the page:

Purchase this eBook to start creating the perfect guest blogging strategy today!

$7.00 – Purchase This is the button

Your cart is empty.
Your cart is empty.

You have not made any purchases

However, when I try to click the button it doesn’t work. I couldn’t see any documentation on why this.

Thanks in advance.
