What is wrong with this code?

In the javascript course I have this instruction for write a code:

"Imagine you have 10 <div> tags on a web page. Each div is 190 pixels wide. Using the two variables in this script, create a new variable named totalWidth that multiplies the width by the numOfDivs variable. Because the width variable is a string, you'll need to use a JavaScript function to retrieve the number value."

Below is the code I wrote: var width = '190px'; var numOfDivs = 10;

var totalWidth = ParseInt(width) * numOfDivs;

Here is the message I get to check my work:

Bummer! There was an error with your code: ReferenceError: Can't find variable:

Any idea, my code is not getting a pass?

parseInt not ParseInt :)
