I am currently talking to squarespace. They are saying that it will only be fixed when there is more demand for it. I am sending them all the forum links where people are asking this question. This is a must for anyone doing ecommerce. Although great, I would hold off on squarespace until they remedy this.
Won't this just trigger the conversion tracker once someone lands on the homepage or on any other page. It says in the code injection area that putting any code in header or footer section is site wide. However, putting it in the confirmation page section also doesn't seem to work.
