Why is my integer not parsing? parseInt(width); var totalWidth = numOfDivs * width;

I'm returning NAN...not really getting it

app.js 
var width = '190px';
var numOfDivs = 10;
parseInt(width);
var totalWidth = numOfDivs * width;

Kyle,

Try putting the parseInt(width) in the assignment to your totalWidth variable, like so:

var width = '190px';
var numOfDivs = 10;

var totalWidth = parseInt(width) * numOfDivs;

Check out this forum post that deals with the same problem.

It looks like your first two lines are correct but there is an error in your last two lines.

parseInt(width); should be part of the totalWidth variable.

Hope this helps!
