I got a little brainbug, and I hope somebody could help me: I cant set a variable as a “part of the object-path”:  
(last 2 lines)

```auto
var yzClick = function(args) {
       console.log(JSON.stringify(args.data)); // OUTPUT: "abc123"
	var yzfield = args.data
	return fetch( YZ_URL2.value)
		.then(function(response) { return response.json(); })
		.then(function(responseObject) {
			console.log(yzfield); // OUTPUT: abc123
			console.log( JSON.stringify(responseObject.fields[0].yzfield)); // OUTPUT: undefined
			console.log( JSON.stringify(responseObject.fields[0].abc123)); //OUTPUT: {"name1":"test","name2:"test2"}
		});
	}

```

I tried different things like `responseObject.fields[0].${yzfield}` or `responseObject.fields[0] + yzfield` ( I know it was stupid)

Any help would be AWESOME 🙂

Gratefully

Could it be `responseObject.fields[0][yzfield]`?
