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)

index.html と sketch.js から始め、libraries ディレクトリ下のスクリプトパスを、報告されている p5.dom.js の 404 と照らし合わせて確認します。参照されている p5 ライブラリが sketch.js より前に読み込まれることを検証します。完了の条件は、404 が解消され、setup 内で createP が ReferenceError なしに動作することです。
