Hi guys,  
I have a js file that contain my application global var such as the user Observable which contains Observables name,email, profilePicture…  
I have defined it like the syntax in the Docs  
(globalVar.js file)

```auto
    var Observable = require("FuseJS/Observable");
    var user = Observable(
        { name: Observable() },
        { email: Observable() },
        { lastname: Observable() },
        { country: Observable() },
        { city: Observable() },
        { phoneNumber: Observable() },
        { profilePicture: Observable() }
        );
module.exports = {
	user:user
};

```

but when i try to update user properties in other pages it doesn’t work  
(login.js file)

```auto
var globalVar=require('js/globalVar');
globalVar.user.value.name.value=json.patient.name;
globalVar.user.value.email.value=json.patient.email;
globalVar.user.value.city.value=json.patient.city;
globalVar.user.value.country.value=json.patient.country;

```

when i have changed the declaration Syntax the update works perfectly 🙂  
(globalVar.js file)

```auto
var user=Observable(
	     {email:Observable() ,
         name: Observable() ,
        lastname: Observable(),
        city:Observable(),
        country:Observable(),
        phoneNumber:Observable(),
        profilePicture:Observable()
        });

```

In which docs did you find the first syntax? It is definitely not correct. 🙂

That code is for an entirely different use case, where you want to have a list of objects with the same type (for instance to iterate over them in an `Each`).

In the first case (your first post) you need _one_ object with different properties, that’s why the 2nd way of declaring it is correct.
