Hi everyone !  
I’m creating an app for my years end application in my school. I try to create an identification system with login, signup, and maybe a facebook connect. However, I had a big problem with firebase, the google chrome console display this message : ‘ReferenceError: Firebase is not defined’ … I don’t understand what happened, because in my section I add :

`<script src="lib/firebase/firebase.js"></script> <script src="lib/angularfire/dist/angularfire.js"></script>`

But it doesn’t work … This is my script for my connexion system :

```
.controller('loginCtrl', function($scope, $state) {
    $scope.loginEmail = function(){
    var ref = new Firebase("https://WizzU.firebaseio.com");
    ref.authWithPassword({
      email : $scope.data.email,
      password : $scope.data.password
    }, function(error, authData) {
      if (error) {
        console.log("Login Failed!", error);
      } else {
        console.log("Authenticated successfully with payload:", authData);
      }
    });
   
  };
})
// Inscription Controller
.controller('signinCtrl', function($scope) {
  $scope.signupEmail = function(){  
 
  var ref = new Firebase("https://WizzU.firebaseio.com");
 
  ref.createUser({
    email : $scope.data.email,
    password : $scope.data.password
  }, function(error, userData) {
    if (error) {
      console.log("Error creating user:", error);
    } else {
      console.log("Successfully created user account with uid:", userData.uid);
    }
  });
};
});`

```

Does anyone could help me ? 😕  
Thank !
