imagine you have 10 <div> tags on a web page. Each div is 190 pixels wide. using the two variable in this script, create a new variable named totalwidth that multiples the width by the number of divs variable. Because the width variable is a string, you'll need to use a javascript function to retrieve the number value.

app.js 
var width = '190px';
var numOfDivs = 10;
var TotalWidth = Parselnt (Width) * (NumOfDivs);

:bulb: JavaScript is case-sensitive

Long story short? You have typos. Quite a few :smiley: The variable is supposed to be named totalWidth... not TotalWidth. You've misspelled parseInt as Parselnt that should be a capital "I" not a lower case "L". Both width and numOfDivs should start with lower case letters. Take a look:

var totalWidth = parseInt (width) * (numOfDivs);

Hope this helps! :sparkles:
