Prompt not appearing

From what I can tell my code is identical to the code shown in the video, however I can't get the first step to show up. When I load the page the prompt doesn't appear.

var input = prompt("Pick a number"); var topNumber = parseInt(input); var randomNumber = Math.floor(Math.random() * topNumber) + 1; var message = "<p>" randomNumber + " is a number between 1 and " + topNumber + ".</p>"; document.write(message);

Hello Andrew,

there seems to be a + sign missing before randomNumber, like this:

var message = " " + randomNumber + " is a number between 1 and " + topNumber + ".";

That will do the trick.

Happy coding!

Thanks, I really need to watch for these syntax errors.

This portion of your code is not well formed:

 message = "" randomNumber

Try looking at the page in the debugger. In most browsers you can right-click on the page and select "Inspect Element". Then look for the console window, and check any error messages there.

I didn't even see that. These syntax errors get me so often. Thanks for pointing it out.
