Cannot find my mistake.

Have looked at this code over and over and cannot find the mistake. Even put it into Codepen and got no error codes. It must be one of those tiny things that you can't see in your own code. Would appreciate help finding the problem. Here's my Codepen doc if that will help. I can already feel that it going to be one of those duh moments. Don't know if those will ever go away...

Hi,

Are you using an updated browser? The syntax covered in this course are not supported by some older browsers. That would explain why it runs in codepen but not in your browser.

Also, what exactly is happening in your browser? Do you see any error messages in your console? Is part of your code running but not all?

const removeItemButton =

like this in you code with no value and there is no semicolon either.

If the mistake you are encountering is that you can't add an item to your list, I have found the problem:

It appears to be an order issue.

In the addItemButton.addEventListener portion of your JS file.

You have to have ul.appendChild(li); before the attachListItemButton(li);

Thanks #Ella Ruokokoski and #Chantal Jenkins. Don't know how the partial variable got back in the code, as I had deleted the entire removeItemButton. Moved the attachListitemButtons(li) and now everything is working.
