Dear Community, i am using Node Red since 3 Months now and did a good learning on it.  
But i am stuck all day long, and not quite good @ js.  
I Have a SMS Gateway Which accepts a payload of: NUMBER\_TEXT\_. e.g: +46887656\_Test SMS \_  
The underscores are for the gateway to know waht is sms and text.  
I have problems to do concatenation...

I want to use a form (dashboard) to send sms.

Form gives following object:

msg.payload : Object  
object  
Number: "1234"  
Text: "test"

I tried following via function:

var txt=msg.payload.Text  
var nmbr=msg.payload.Number

var msg1 =  
{  
payload:nmbr  
};  
var msg2 =  
{  
payload:txt  
};

msg.payload = "";  
msg.payload += msg1;  
msg.payload += "_";  
msg.payload += msg2;  
msg.payload += "_";  
return msg.payload;

Can anyone help me to concat taht string??? I am Totally stuck ...

Well you could use a function and do

```
msg.payload = msg.payload.Number + "_" + msg.payload.Text + "_";
return msg;

```

To concatenate the two parts - inserting the underscores that you seem to need also.

A slightly less "programming-language" way to do this would be a simple `template` node --

it uses _mustache_ syntax to do variable replacement within the surrounding text, so your use case could be written as `{{payload.Number}}_{{payload.Text}}_`

_Note that the leading_ `msg.` _needs to be left off of your variable names, since the entire `msg` object is already used as the source of those variables_
