JavaScript JavaScript Basics (Retired) Working With Numbers Numbers and Strings

I am not able to get past this questions, and I have no idea what I'm doing wrong. Please help:)

Let's assume we have 10 <div> tags on a page. Each is 190 pixels wide. Using the two variables in this script, create a new variable named totalWidth that multiples the width by the numOfDivs variable. You'll need to use a JavaScript function to retrieve the number value from the string in the width variable.

app.js 
var width = '190px';
var numOfDivs = 10;
var width = parseInt(width);
var totalWidth = width * numOfDivs;
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="app.js"></script>
</body>
</html>

You don't want to reset the width variable. You just want to parse it, leaving the original in tact.

var totalWidth = parseInt(width) * numOfDivs;

That makes perfect sense in retrospect. Thank you, thank you, thank you Colin Bell!
