Can someone please advise how to add all "pv\_estimate" values in the incoming message together and send the sum to the output? Thanks

I am guessing that the objects you have shown are elements of a payload array, as your image leaves alot of info out.

Feed the payload into a change node  
set `msg.payload`  
to JSONata J: `$sum($$.payload.pv_estimate)`

If that fails please present an input object that is copyable.

I am still guessing that that info is in payload  
`$sum($$.payload[0].estimated_actuals.pv_estimate)`

Please show image of debug showing full msg object, if this did not work.

Yes, but "estimated" array is four times, and each have 48 "pv\_estimate" records.  
$sum($$.payload[0].estimated\_actuals.pv\_estimate) works for only first

I saw your image as one array. Then your copyable object was so large i did not see the 4 arrays. Maybe next time cut it down to 3 objects per array element for testing.

Anyway

For 4 separate array results `$$.payload.$sum($.estimated_actuals.pv_estimate)`

For the total of all `$sum($$.payload[*].estimated_actuals.pv_estimate)`
