I can' seem to figure out what the error is for this code. I get the error message "global leak detection: totalWidth".

script.js 
const width = '190px';
const totalImages = 10;
totalWidth = parseInt(width) * totalImages;

the problem may happen when you try to parse a string which consists of not only numbers.... haven't tryed your case on my computer, but try removing px from const width and append px unit at the end of total width.

I hope this helps!

Hey terd47,

You were very close with this challenge, all you have to do now is to declare a totalWidth variable by using a const keyword.

const totalWidth = parseInt(width) * totalImages;
