Hello People of node red believers.  
I am a problem with adding ( sum ) of an memory variable with a fresh variable like following.

TotalToday = SaveOpname + TotalToday

But is not working ( still get the same sum of the value's )  
Meaning of this flow ( function ) is that the value is keep adding on the value before.

example of my function

let TussenVar = {};  
let TotalToday = {};  
let SaveOpname = {};  
let Opname = {};  
TotalToday = parseInt(flow.get("TotalToday"));  
SaveOpname = parseInt(flow.get("Opname"));  
TotalToday = SaveOpname + TotalToday;  
msg.payload = TotalToday;  
return msg;

I think this is an easy one , but stills failures on this easy flow.

Is there a tric to do what i want ?

this is the flow:

So where do you save TotalToday back to the flow variable?

something like this ?

let TussenVar = {};  
let TotalToday = {};  
let SaveOpname = {};  
let Opname = {};  
TotalToday = parseInt(flow.get("TotalToday"));  
SaveOpname = parseInt(flow.get("Opname"));  
TotalToday = SaveOpname + TotalToday;  
TotalToday = (flow.set("TotalToday"));  
msg.payload = TotalToday;  
return msg;

ps: for me is this more than try and error 😉

```

NaN is now the output , but after give a new timestamp on initialise than it give me a output without the sum.

Also not working with this try

let TussenVar = {};  
let TotalToday = context.get('TotalToday') || 0;  
let SaveOpname = {};  
let Opname = {};  
TotalToday = parseInt(flow.get("TotalToday"));  
SaveOpname = parseInt(flow.get("Opname"));  
TotalToday += SaveOpname;  
context.set('TotalToday', TotalToday);  
msg.payload = TotalToday;  
return msg;

You are mixing context and flow context storage, also you can not store the opname and retrieve it before it is stored.

```auto
let SaveOpname = 0;
let TotalToday = parseInt(flow.get("TotalToday") || 0);
SaveOpname = parseInt(msg.payload.power);
msg.payload = SaveOpname + TotalToday ;
flow.set("TotalToday", msg.payload);
return msg;

```

Finaly 😄 that was a part of my life

This is the function that do the correct thing I want:

let TussenVar = {};  
let TotalToday = {};  
let SaveOpname = {};  
let Opname = {};  
TotalToday = parseInt(flow.get("TotalToday"));  
SaveOpname = parseInt(flow.get("Opname"));  
TotalToday += SaveOpname;  
flow.set("TotalToday",TotalToday);  
msg.payload = TotalToday;  
return msg;

Hello Dimpie,

Welcome to the community and good to see that you found your first solution here. 🙂

I just want to point you to an alternative solution I found in the forum these days to add/ increment easily a value to a global variable:

> [@Increment a global variable with a change node](https://discourse.nodered.org/t/increment-a-global-variable-with-a-change-node/44893/2):
>
> Yes that's possible' Set Global metric JSONata expression $globalContext("metric") + 1

Might reduce lines in the code 🙂

Cheers  
Ranki

Hello Ranki, Thanks for that solution. It looks a nice extra for later.  
But for now I think its not working in my case. I want to add with a variable. So i try this with Json change node like your post but with an extra variable :

$globalContext("SaveOpname")+$globalContext("Opname")

but give's me every time the same "Opname" Value.  
It was a good try for me to learn more about that Json string.

See the flow
