I am putting in:
var width = '190px';
var numOfDivs = 10;
var width = parseInt(width);
var totalWidth = width * numOfDivs;
The program keeps telling me " Bummer! Did you use the var keyword to create the totalWidth variable?"
Am I doing something wrong?

Check the JavaScript console to see which line the error is coming from. I think you'll be surprised. The error is actually in line 3 ( var width = parseInt(width); ).
Remember that you don't need to use 'var' again when using the same variable. On line 4 of your code, you redeclare 'width' using 'var'. I would recommend eliminating altogether the need for another variable (line 3) and just make totalWidth equal to width (parsed as an int) times the number of Divs. (I tried explaining it without just writing the code for you).
EDIT: formatting
