What am I doing wrong?!?

added

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

and it says that is wrong. I've typed different variations of this.

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

what am I doing wrong?

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>

Hey Erik -

Super close I think. All you need is to remove the parenthesizes around boxWidth in your parseInt call:

  var numWidth = parseInt("640", 10); => should be parseInt(boxWidth, 10);

you should pass in boxWidth as argument, not the number.

var numWidth = parseInt(boxWidth, 10);
