If you are using a laptop or desktop to do your coding, make sure to use the console window of your browser to look for errors in your code. In programming, looking for and correcting errors is called "debugging." Below I have a screen shot of my code, the (empty) browser, and the error message I get from the Chrome console. Don't worry if error message itself doesn't make sense, that is something that comes with time, the important part is to look for the line number, in this case line 9. The console will always try to tell you about where it ran into a problem. In this case, I didn't include the quotes to end the message for the alert.
