Let's assume we have 10 <div> tags on a page. Each is 190 pixels wide. Using the two variables in this script, create a

I don't understand why isn't working

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

Could you please complete your question. In my opinion, var declarations in your js are fine, buy you're doing nothing with them.

Hi Davide,

The casing of numOfDivs on the following line is the issue:

var totalWidth = numOFDivs * parseInt(width);

The variable is set as:

var numOfDivs = 10;

so the line below should be:

var totalWidth = numOfDivs * parseInt(width);

Notice the lower case F.

Hope that helps.
