Having difficulty accessing information from the parent scope

As I continue to dive into AngularJS, I've encountered some challenges with scopes in my current project.

Here is my controller and directive setup:

angular.module('myModule', [])

.controller('myController', ['$scope', function($scope) {
  $scope.parentVariable = "Test";
}]);

.directive('myDirective', [function(){
  return {
    restrict:'AEC',
    link: function(scope, element, attrs) {
      var child = scope.$eval(attrs.myDirective);
    }
  }
}]);

Now for the HTML snippet:

<div ng-controller="myController"
  <div my-directive="parentVariable"></div>
</div>

I am attempting to access the value of parentValue, yet upon running the code, child remains undefined.

If you come across a few typos, simply correcting them will fix everything. It's important to note that when using a variable in the DOM, it needs to be set as a scope property. Here's an example:

angular.module('myModule', [])

.controller('myController', ['$scope', function($scope) {
  $scope.parentVariable = "Test";
}])
.directive('myDirective', [function(){
  return {
    restrict:'AEC',
    template: '<p>{{child}}</p>',
    link: function(scope, element, attrs) {
      scope.child = scope.$eval(attrs.myDirective);
    }
  }
}])
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myModule" ng-controller="myController">
  <div my-directive="parentVariable"></div>
</div>
