Creating a collaborative document editor with Meteor [on hold]

Task: I am trying to create a collaborative document editor using Meteor and have used the following if statement to create a new document within a MongoDB database:

        if (!Documents.findOne()){// no documents yet!
            Documents.insert({title: "my new document"});
        }
      });
}

After running the app at : [http://localhost:3000/] and inputting the following code to the Console area in inspect:

Documents.findOne()

Problem: Uncaught reference error in the Console:

VM170:1 Uncaught ReferenceError: Documents is not defined

Outcome: I would like "my new document" to be found for the following message to appear:

Object {_id: "", title: "my new document"}

This is so I know my code is working and a new document has been added the the database.

How can I make "my new document" appear alongside the Object id?
