Hi!

I have an array with two values. Once cat\_id. and pro\_id.  
Is it possible to add all the same pro\_id together?

Here's an example.  
 ![Bildschirmfoto 2022-08-06 um 11.05.50](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/8/e8ed4943d8a0defb451e504e8a5eca2f15ec18a5.png)

array  
0  
cat\_id = 3114  
per\_id = 3114

1  
cat\_id = 3114  
per\_id = 3474

result

cat\_id = 3114  
per\_id = 3114.3474

I hope someone can help me.

Thanks in advance

Yes it's possible using a change node and JSONata or in a function node
