Confused

It keep asking me to Make sure you declare the coordinates array with the var keyword. not sure what I'm doing wrong and what that means

script.js 
var coordinates = [ [1,2], [2,3], [3,4], [9,10] ];
var coordinates = [ [1,2], [2,3], [3,4], [9,10] ];
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

A variable can only be declared once, but you have two of the same code lines!

Delete either duplicate and you will pass the challenge.
