404 error in chrome console. Not allowing me to run program.

Hello, I completed an assignment in my workspace and it ran just fine, but then when I was completing another assignment, it wouldn't let me run the code. The 404 error message kept coming up in the console. I tried to run my previous program in the workspace, to make sure it wasn't a syntax error, but it got the same message (even though I hadn't made any changes to the code and had updated the html file). I updated my mac and chrome, shut down my computer, tried running the same workspace on another computer, and nothing has worked. I even tried running another program I had made from a previous workspace (that had run perfectly before) and it wouldn't run. The same error message kept popping up in the console: Failed to load resource: the server responded with a status of 404 (Not Found) /favicon.ico:1

Any help would be much appreciated...I've spent the last few hrs trying to figure this out.

Thank you, Hannah

Hello Hannah! We'll need the complete code to be able to assist you. It can be so frustrating when something's not working correctly, to help you we'll need to try replicating the issue.

/* And then the code for the html:

Thank you!

On the line: <script src="js.random.js"></script>, if your file is named random.js and is located in a directory named js, then the source attribute should be: src="js/random.js" (note the slash instead of a period).

Otherwise, this appears to work just fine. But there could be some other issue based on file organization. When you need help with a workspace problem, always make a snapshot of your workspace and post the link to it here.

Ahh! Thank you so much! It worked, and I tried it on a couple different programs to make sure.
