Parsing Numbers From Strings Challenge 1 of 2

Any clues to the answer to this challenge. I've tried every variation I can think of. No mention in the forum for this. Little Help...

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.

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

You are supposed to extract the number from the boxWidth's variable not from a string literal. So swap out the number you are using for the variable name boxWidth.

Hi Michael,

That code challenge wants you to parse the number out of the boxWidth variable. You are trying to parse it from a string literal "640". So the answer would be in the form:

var targetVariable = parseInt(sourceVariable, radix);
