I currently have an Array aggregator that has 3 collections with different itemCost values.

I want to add all of the itemCost values together to allow me to take the total of them, how would I got about this?

Typical, I posted this then 5 minutes later I managed to fix the issue myself.

I used an Iterator to retrieve the array which included the itemCost and then used a numeric aggregator to ‘SUM’ them together.

Try using,

> {{sum(map(“array”; “itemCost”))}}
