JavaScript JavaScript Foundations Numbers Parsing Numbers From Strings

Need help with a javascript quiz question.

Heres the question:

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"; My answer: var numWidth = parseInt(“640px”, 10);

I believe with your code, you receive the error: "Sorry! That's not correct. A correct answer will use the form: var numVariable = parseInt(stringVariable, radix);"

Which of course explains that the challenge is looking for you to use a variable, in this case: boxWidth.

Try this

      var boxWidth = "640px";
      var boxHeight = "480px";

      var numWidth = parseInt(boxWidth, 10);

That was the problem. I was not using the variable name. Cheers!
