Don't each of my objects have two values?

Do I have to have a question and answer format like the one in the video? I tried that and that also didn't work. It says each object should have two properties/values, so are the two number values in each object no good?

script.js
var objects = [
  {object: 13, object: 20 },
  {object: 10, object: 40},
  {object: 9,  object: 30 }
];

your properties in the objects need to be different. you have both objects with both the properties object. each property needs to be different You have

var objects = [
  {object: 13, object: 20 },
  {object: 10, object: 40},
  {object: 9,  object: 30 }
];

the second property in each object needs to be different. anything will do like this

var objects = [
  {object: 13, object2: 20 },
  {object: 10, object2: 40},
  {object: 9,  object2: 30 }
];

this is just an example. you can name your properties differently

Think of the exercise in terms of something in the real world and it'll be easier to understand how it works I think. Assign an object to your hometown then create a property for 'high school' and fill it with a string. Create a property for population and fill it with a number. Create a property for.....idk, movie theaters and fill it with an array of the different ones around town. Then repeat the process for the town next door.

var cities = [
{name: Minneapolis, state: MN, latitude: /*whatever it is*/, longitude: /*no idea*/},
{name: Chicago, state: IL, latitude: /*who knows*/, longitude: /*probably Google*/}
]

That's what worked for me anyway.
