ParseInt coding problem

A little help here. Am I missing something?

index.html 
<!DOCTYPE html>
<html lang="en">
  <head>
    <title>JavaScript Foundations: Parsing Numbers From Strings</title>
    <link rel="stylesheet" href="core.css">
    <script>
      var boxWidth = "640px";
      var boxHeight = "480px";

      var numWidth = parseInt("640", 10); 


    </script>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Parsing Numbers From Strings</h2>
    <script src="viewer.js"></script>
  </body>
</html>

10 is supposed to be the base decimal right?

I read on the Teacher's Note that newer browsers state 12 instead of 10 so I don't know.

pass in boxWidth variable to the first parameter of the parseInt() method.

So basically it's this var numWidth = parseInt(boxWidth, 10);

Yep now I got it. Thanks.
