CSS CSS Foundations Backgrounds and Borders Box Shadows

What am I missing in this line?

.box { box-shadow: 10px 10px 5px 15px rgba(,#222) ; }

index.html
<!DOCTYPE html>
<html>
<head>
    <title>Box Shadows</title>
    <link rel="stylesheet" type="text/css" href="page.css">
    <link rel="stylesheet" href="style.css">

<body>
    <div class="box"></div>

</html>
style.css
/* Complete the challenge by writing CSS below */

.box {
  box-shadow: 10px 10px 5px 15px rgba(0,0,0,#222) ;
}

Create a drop shadow for the .box div. Make it appear 10px to the right and 10px down, with a spread radius of 5px, a color of #222, and a blur radius of 15px.

Hello. The last value in the RGBA color should be a number between 0 and 1. It could be something like 0.2, 0.8, etc... that value is supposed to be the alpha, so: 0.0 is fully transparent and 1.0 is fully opaque.

You have your blur radius and your spread radius mixed up. Switch those, and change the color to just #222. It asks for the hexadecimal color of #222, not an rgba color.

Thanks for that answer.
