What am I doing wrong?

The Challenge questions is "A variable named "boxWidth" already exists with a value of "640px". Create a new variable named "numWidth" and use the "parseInt" method to extract the numeric value from boxWidth's string value."

 <script>
      var boxWidth = "640px";
      var boxHeight = "480px";
      var numWidth = parseInt("640px", 10);


  </script>

Gary, I went ahead and removed the duplicate post. Could've been some lag on the net and it got double posted. Hope you're enjoying Treehouse.

I think they want you to extract the value from the variable:

var numWidth = parseInt(boxWidth, 10);

No problem. Most of the time it's something small that you just overlook.
