Hi Martina, thank you for the answer request. It was a pleasure.

There was a missing closing curly bracket in your app.js file:

angular.module('myApp', [])
.controller('myController', function($scope) {
  $scope.user = { name: 'Alex' }
})
.directive('myDirective', function () {
  return {
    require: 'ngModel',
    priority: 1,
    link: function ($scope, $element, $attrs, ngModelCtrl) {
      ngModelCtrl.$render = function () {
        var contents = ngModelCtrl.$viewValue;
        $element.hallo('setContents',contents);
      }
  }
  }
});

I found the error by using the developer tools console. I highly recomend to learn how to use it if you do not already know. https://teamtreehouse.com/library/javascript-basics/introducing-javascript/the-javascript-console Hope this helps.
