Hi there,

Just a couple things keeping this from running:

  • In your index.html, it's currently just looking for 'helpers.js', but the file is actually in the js folder. That means you need to add the folder to the address, like this:
<script src = "js/helpers.js"></script>
  • In helpers.js, there is a comma on line 7, after the playList variable. To fix this, just clear that line.

After I did these two things, it loaded with your list of songs - good luck!

Bless you Katie! Thank you for the rescue again. Just to be clear, I'll like to know why the playlist are numbered. Is it because the items in the array is written out in separate lines like this?

var PlayList = [
'Galway Girl' ,
'Shape of You' ,
'Hills' ,
'Stupid Song'
];

Good question!

It's numbered because of the printList() function. If you check out how it writes the html, it uses the <ol> tag - that's an ordered list. That means that the list defaults to numbered values.

Wonderful! Thank you so much. I need to pay a lengthy visit to css an Html since I started with JS, but I don't know the best time to do that. I'v always wondered if this JS course will ever end
