Not accessing the property Value

I'm not understanding how I'm not accessing the property value.

I'm using bracket notation, and I've compared it to the previous video.

script.js 
var shanghai = {
  population: 14.35e6,
  longitude: '31.2000 N',
  latitude: '121.5000 E',
  country: 'CHN'
};

for ( var key in shanghai) {
  console.log(shanghai.key , ': ', shanghai[key]);
};
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

That creates the following prompt:

Oops! It looks like Task 1 is no longer passing.

Because the challenge is just asking for the property names, and not the actual values.

I just showed you how you can accomplish both;

for ( var key in shanghai) {
  console.log(key);
};
