5,041 PointsYou have a couple of issues going on here. First, as noted in the other answer, you have a left parenthesis before the parseInt() function and you are using the value of the 'width' variable (190px) instead of the variable itself : parseInt (width). Also you have a syntax error when calling the numOfDivs variable. The variable is defined at the start of the code page with standard javascript formatting of capitalizing the first letter of every word starting with the second word. Your solution calls numofDivs leaving out the capital O in Of. Javascript reads this as a different and undefined variable from numOfDivs.

A couple of things to think about. Using the parseInt method is correct, but it is it's own method so you do not need a "(" before you call the method. Second, the great thing about variables is that you can use them and do stuff with there values. so in this case, instead of using the string '190px' to parse, try parsing the variable width. You have the last part down you want it multiplied by the numOfDivs variable.
