Use `RED.util.getObjectProperty`

See similar thread here : [Alternatives to eval() - #2 by Steve-Mcl](https://discourse.nodered.org/t/alternatives-to-eval/50550/2)

in your case...

```auto
var i = 1; // <<get from somewhere else. Hard coded to 1 for demo purposes
var varName = `section_${i}`
var v = RED.util.getObjectProperty(msg.payload, varName); 

```
