Good evening

I have a function node that manipulates text and outputs in the following variables.

var out = {payload: [i] + StrIO[i] + Temp[i] };  
node.send({payload:out});

I am trying to feed this value into a change node but I have noticed using a debug node that it shows it as payload object not payload string which means the change node does not work.  
If I feed my value into the change node using an inject node it works.

So I guess I need to convert the msg object value to a string

Many thanks In anticipation

regards  
Andrew

You’ve stacked your payload inside another payload. Maybe just return out ?

As `i` is a number it will try to do arithmetic addition instead of string. Convert `i` to a string before concatenating them. Or even better use string interpolation.

You have created an object called `out` that contains a property called `payload`. Then in the `node.send()` call you create another object containing a property called `payload` which itself contains the `out` object.  
The result is that when you receive that message in the next node `msg.payload` contains your `out` object.  
Possibly what you meant was  
`node.send(out)`
