How do I add a Facebook Pixel to my Shopping Cart and Checkout page?

@Mark_Dawes,

Edit the shopping cart theme you want to use. There are tabs you can click and on is html. In that there are separate edit spaces for header/footer/body etc. FB pixels I believe normally go in the header (but it might be footer) but see if FB specifies this. Just past the code snippet in which ever section they recommend and that should be it. As long as you use that theme for your shopping cart it should trigger as coming from FB.
