Solution to Numbers and Strings challenge

Hi, what is the solution to the Numbers and Strings challenge. I have tried the following, but get a syntax error Paser error:

var totalWidth = parseInt(width) x numOfDivs;

2 Answers

hello sperera your syntax is right but you are not using the multiply operator. it looks like you are using x instead of *

// you wrote
var totalWidth = parseInt(width) x numOfDivs;

but it should be

var totalWidth = parseInt(width) * numOfDivs;

i hope this solves you problem

oh my goodness.. yes! thanks a lot!

No, that does not solve it. These are the variables used to calculate the totalWidth:

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

So parseInt is required to change the width from string to int.

I see, I presumed you already declared a width variable that held a integer from using the parseInt method. I didn't see the video.
