This is an accepted solution.
Hey. It's close. I checked your product page. I see the output value for ecomm_totalvalue is 1.099 on https://palmswear.com/collections/novinky/products/leginy-palmswear-perform-red. So that is incorrect. You will need to adjust that value to suit the currency on your store.
You also need to map the custom dimensions to their appropriate field. I have written a book that shows you how to setup dynamic remarketing in Shopify.
