Hi, I have nested objects in an array. The objects are the same structure. I want to add together all [array][amount] values (which are all numbers) where x can be any number up to around 40, to create a new field [amount-sum] where this arithmetic is stored.

There is not a set amount of objects in each array and so this method does not work:

event.set( "amount-sum", event.get( "[array][0][amount]" ) + event.get( "[array][1][amount]" ) + event.get( "[array][2][amount]" ) )

Thanks,

Tom
