When I click on your ranger examples it errors out:

> TypeError: Cannot read properties of undefined (reading ‘high’)
> 
> 🌸 p5.js says:  
> [sketch.js, line 34] Cannot read property of undefined. Check the line number in error and make sure the variable which is being operated is not undefined.

Ah, you’re missing a set a parentheses in the demo code on that line. Should be

```auto
            gui.$('rgr0high').text(info.high.toString());

```

It is not a bug in the library rather a mistake in the sketch code which I have corrected.  
_Just noticed you found the bug already._ 😇

If you force refresh the page or visit the [sketch](https://editor.p5js.org/quark-js/sketches/eXmuaaWOv) in the web editor here I think you will find it works fine. 😃
