Hello everyone! I am on the third task of the two-dimensional arrays challenge

I can't find what i did wrong. Whenever I enter the code, it says task 1 is no longer passing. If someone could help me see what mistake i made, I would be grateful.

script.js
var coordinates = [
  ["x", "y"]
  ["love", "joy"]
  ["breakfast", "dinner"]
  ["start", "finish"]
  ]
index.html
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

You forgot the separators.

Any syntax error invalidates the entire script; and since the challenge re-checks the tasks in order, it can misinterpret the problem as being in "task 1".

But the actual issue is that between the individual sub-arrays, you need commas (",").

Oooooh, I see. Thank you, I appreciate your help! I always seem to mess up on syntax.
