I am trying the code challenge but on the first question it is asking for var numWidth using parseInt. But after inputting the correct code, it says wrong we need numVariable using the parseInt as well, but it does not recognizes the numVariable?

I have tried to browsers and reset all cache and cookies in both.

var numWidth = parseInt("640", 10);
var numVariable = parseInt("480",10);

Any idea?

Hi KeVin,

I don't see anything about a variable named numVariable. Also, you want to do something more like this: parseInt(boxHeight, 10).

Question 1.) 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.

Question 2) Similarly, a variable named "boxHeight" already exists with a value of "480px". Create a new variable named "numHeight" and use the "parseInt" method to extract the numeric value from boxHeight's string value.

I keep getting this on the first question.

Bummer! Sorry! That's not correct. A correct answer will use the form: var numVariable = parseInt(stringVariable, radix);

is this not correct? var numWidth = parseInt("640", 10);
