What could possibly be wring with my code?

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

This code works if it's used in a browser, but for some reason the treehouse platform doesn't like the multiple declarations of width. If you remove the var keyword on the second line, it works.

var width = '190px';
width = parseInt(width);
