Hello @ValPiwik ,
Did you have a chance to look into this article How to set up ecommerce tracking? - #2 by pp.support? The data layer structure is different, but it’s just a matter of adjusting the variables. Please make sure there is a loop that iterates through the cart (you need to add each product separately). You can use the tracker debugger to check if the variables were correctly assigned.
Thanks,
Piotr
