Angular Expression doesn't display

I've got a bit of a mystery here which I'm hoping some in the know about Angular will be able to resolve.

It's a simple example of using ng-repeat to display a block of information 3 times. There's 3 values in an object of the controller js file. Name, Description and Price. But price won't show up. Any ideas why?

  ];

}]);

Hi Jonathan,

You appear to have your ng-repeat attribute on the wrong line, to me it makes sense to have it on the .row above since you're using columns, try the below.

<div class="row" ng-repeat="appetizer in appetizers">
  <div class="item col-md-9">
    <h3 class="name"> {{ appetizer.name }} </h3>
    <p class="description">{{ appetizer.description }} </p>
  </div>
  <div class="price col-md-3">
    <p class="price">{{ appetizer.price }}</p>
  </div>
</div>

Hope that helps.

Smashing! This worked thanks!

The original task wasn't showing up properly when I had the ng-repeat where you suggested it. None of the expressions were showing up. So I moved it and then the name and description showed up but not the price. How odd but it looks like we've found the answer. :)
