var width = '190px'; var num = parseInt(width); var numOfDivs = 10; var totalWidth = (width * numOfDivs);

Hi Chyno, This is the code I used.

And Krzysztof saves the day! If I may ask, where did you learn this? This pattern wasn't in the lesson/video nor in the teacher's notes.

Well sometime it's good to look for some methods/functions documentation to see what does it do before you use them. Like in this case read this MDN documentation about parseInt ;)

I took a look at this challenge to check if numOfDivs is a string variable or an integer and if width is a string you have to parse with.

So in this case if numOfDivs would be a string variable your function would look like:

var totalWidth = width * parseInt(numOfDivs);

But in this case it's integer and width is a string you have to parse so your code is like: 

var totalWidth = parseInt(width) * numOfDivs;

I keep getting the same message and here is what I did: var width = '190px'; var width = parseInt(width); var numOfDivs = 10; var totalWidth; var totalWidth = width * numOfDivs;

keep getting the message: Did you use the 'var' keyword to create the 'totalWidth' variable?
