JavaScript Objects and Properties

The code challenge asked to create an object called paris with 3 properties (population, latitude and longtitude) the values are given in the challenge. But i keep getting an error message saying that my properties for the object are not stated. Can someone help me find out what is wrong with my code? Much appreciated.

script.js 
var paris = {
  population : '2.211e6',
  latitude : '48.8567 N',
  longtitude : '2.3508 E'
};
index.html

Hey Iris,

I would check your spelling for the third property. The question is asking for the exponential notation. Your value for your first property is a string. I would remove the quotations and you should pass.

Hi Kareem,

Thank you for your reply. I have removed the quotations but it still didn't pass the challenge. However when I tried repeating the same steps in an external text editor, it worked fine in the JavaScript console. So I'm still not sure what the problem is, with my answer to the challenge. But thank you for checking through , much appreciated!
