Hi !

First sorry for my bad english 🙂

I'm trying to make a node-red function to send two msg.

One of these message contain a variable.

The messages must be like this:

- msg1: NEXTION,conschauf.txt="19"
- msg2: NEXTION,p1.pic=8

The value "19" of msg1 is stored in node-red by an other node ( flow.set('consigneconfort', msg.payload.result[0].SetPoint); )

I have write this function:

```auto
msg.topic = "ECRAN-ENTREE/cmd";
if (flow.get('modeconfort') === "On") {
    var consigne = flow.get('consigneconfort');
    var msg1 = { payload: 'NEXTION,conschauf.txt="consigne"'};
    var msg2 = { payload: 'NEXTION,p1.pic=8' };
}
return [msg1, msg2];
```

but the result is:

- an "Invalid topic specified" error
- the first message is like this: "NEXTION,conschauf.txt="consigne""

Someone can help me to find the problem, please ?

Regards,

---

To insert the value of `consigne` in the message payload, you can do the following.

```auto
var msg1 = { payload: `NEXTION,conschauf.txt="${consigne}"`};

```

As for the function - you are settings `msg.topic` but then return the `msg1` and `msg2` objects that don't have `topic` set. If you want the topic property to be set on those objects, you will need to set it:

```auto
var msg1 = { payload: `NEXTION,conschauf.txt="${consigne}"`, topic: "ECRAN-ENTREE/cmd"};
var msg2 = { payload: 'NEXTION,p1.pic=8', topic: "ECRAN-ENTREE/cmd" };

```
