Thank you for your response bcworkz.
The plugin I used to insert the pixel is “Add Tracking Code to WC Thank you Page.” The plugin allows you to paste in the pixel which was given to me by SocialLadder. The pixel was not generated from a plugin, a generic pixel was sent to me and they asked me to input the correct variables in the bracketed areas. For instance [orderid] needs to be placed the the variable that will pull the actual orderid when a purchase is made.
