I am learning the html_css based on your tutorial. I use Atom as my editor. I put the p5.js, p5.dom.js, and p5.sound.js into one folder called libraries. And then put this folder and the index.html, the sketch into one folder called html_css_learning. However, when I write the code"createP("Your roll point is like below.");" , there is an error "CreateP is not defined". and "libraries/addons/p5.dom.js 404 (Not Found)"

I am new for programming. Please help!

**Here is my libraries.**
```html

body {padding: 0; margin: 0;}

This is my first website!

"Welcom to my website. I am looking forward to seeing how it goes!"

```

**This is the error.**
GET http://127.0.0.1:3000/html_1/libraries/addons/p5.dom.js 404 (Not Found)

Uncaught ReferenceError: createP is not defined
at setup (sketch.js:5)
at p5. (p5.js:46551)
at p5. (p5.js:46486)
at new p5 (p5.js:46775)

Empieza con index.html y sketch.js; después, comprueba las rutas de los scripts en el directorio libraries en relación con el 404 reportado para p5.dom.js. Verifica que las bibliotecas p5 referenciadas se carguen antes que sketch.js; se considera terminado cuando el 404 desaparezca y createP funcione en setup sin un ReferenceError.
