Google Tag Manager - Grab nested value from data layer

Question

I want to grab the price key in the addToCart datalayer. It does not work by simply creating a price variable - I get the value Undefined. How do I grab a key that is nested this deep?

Answer 1

Create new variable with this value:

ecommerce.products.0.price

You need to use dot notation to access nested dimension.

Answer 2

inserted this as a variable and just referenced the datavariable name in GTM.

ecommerce.add.products.0.price
