Open modal from controller?

I am trying to open a modal from a controller but I get an error can’t read property ‘show’ of undefined

.controller('LoginCtrl', function($scope, $state, $ionicModal, Login) {

  $scope.user = [];
  $scope.modalMsg = [];
  $ionicModal.fromTemplateUrl('modal.html', {
    scope: $scope,
    animation: 'slide-in-up'
  }).then(function(modal) {
    $scope.modal = modal;
  });
  $scope.openModal = function() {
    $scope.modal.show();
  };
  $scope.closeModal = function() {
    $scope.modal.hide();
  };
  $scope.$on('modal.hidden', function() {
    $scope.modal.remove();
  });
  $scope.$on('modal.removed', function() {
    // Execute action if needed
  });

  $scope.login = function(user) {

    if (Login.validate(user)) {
      alert("YAY!");
    } else {
      $scope.modalMsg.title = "ERROR!";
      $scope.modalMsg.content = '<p>Please re-enter your username and password.</p>';
      $scope.openModal();
    }

  };
})

So I have a validate and on not entering a username or pw it fails. so $scope.openModal() is happening, but the modal is undefined, how am I doing it wrong???

i figured it out was just a simple thing. the path to template was wrong. so instead of error about this, it just returns undefined.
