I have this payload and I would like the min and max value.  
I do not know if I'm doing well but I get nothing.  
{"bins":[{"min":4,"max":3}] }  
let min = payload.bins.min  
let max = payload.bins.max

Help Please,

You've missed the fact that the min/max values are an object **within an array**.

Try something like:

```javascript
let min = payload.bins[0].min
let max = payload.bins[0].max

```

You can use the debug panel to get the path to a value. Hover over the value within the panel and its one of the options that appears
