Hello,  
I want to select various part of a list using global variable.  
I have a global variable named 'Cue'  
How can I replace the 6 in Payload[6] by the value of Cue?  
I have tried a function node with:

```auto
var count = global.get('Cue');
msg.payload = msg.payload + "[" + count + "]";
return msg;

```

But it doesn't work…  
Thank you in advance for your help,  
Jacques

```auto

msg.payload = msg.payload[count];
return msg;

```

... should do it! 👍
