So you're close but you've got some things you need to adjust. Ajax is async which means that you're waiting on a server response. You need to fill your data once you have that piece of data. Note you will not be able to reference fbjson until AFTER the getJSON has fired and completed.

According to the jQuery documentation for getJSON

you need to have a callback similar to this - 

var fbuid = 'zuck';
var fbjson;

$.getJSON( "https://graph.facebook.com/"+fbuid, function( data ) {
  fbjson = data;
});

Notice I assign the fbjson in the callback to data which is the server response. now you can reference it as 

fbjson.id
