Conversion pixel not working for facebook

Hello,

I am following this http://www.mitchcanter.com/conversion-pixels-woocommerce/

and trying to insert a facebook tracking pixel in each of my products on the advanced tab on each of my products in woocommerce.

I have had a number of sales on my website at 88herbs.com but for some reason the sales aren’t being registered on facebook for each of my products. I was just wondering what I might be doing wrong or what can be done? Thanks in advance for the support! I’m very excited to get this working.

Thanks again! My website is 88herbs.com
