I.m sure this has been asked before but can't find a solution and tried searching for the relevant javascript solution but didn't help. I'm trying to get 2 values out of a function and get "Function tried to send a message of type string"  
Function code below.

global.set("pushed", 1);  
global.set("override", 0);  
var p = global.get("pushed");  
p=p.toString();  
var o = global.get("override");  
o=o.toString();  
var msg1=msg.payload;  
var msg2=msg.payload  
msg1.payload=p;  
msg2.payload=o;  
return [msg1 , msg2];

Change

> [@podi62](#):
>
> var msg1=msg.payload;  
> var msg2=msg.payload

to

```auto
var msg1={};
var msg2={};

```

That worked perfectly. Many thanks. Hope it helps other newbies to JS and Node-Red.

I think you should also carefully read the manual [https://nodered.org/docs/user-guide/messages](https://nodered.org/docs/user-guide/messages) and do some experiments to understand how to deal with msg Object and its properties.
