Hello,
I am using below code to retrieve data from a payload.
```auto
var row = flow.get("row");
msg.payload = msg.payload[row].payload;
return msg;
```
This is not working. Is there a way to set make the number variabel?
msg.payload[0].payload, msg.payload[1].payload, msg.payload[2].payload, etc.

This works well if:
f`low.get("row")` gives a number
and
incoming `msg.payload` carry an array which has that amount of members so it does not look outside of array boundaries
and
incoming `msg.payload[the number of the row]` has property called with name `payload`.
If you make sure those conditions are met, It should work flawlessly.
Use debugging options to be sure.
Also such kind of functions should have some fallback for situations when conditions are not met.
Depending on what the real case is but I'd start with easy things like:
```auto
var row = flow.get("row")
if(row == undefined){
row = 0
}
```

the value had to changed to a number, that did the trick
