[orkut-developer] Getting the friends count

[aptas]

Hi..
I am trying to format the list of friends which I have fetched using
the orkut API.
I am trying to get the total number of friends (friend count) so that
I can loop it and arrange the friends (3-4 friends in one row).
I tried using getTotalSize() but it is not working. Can you please
suggest me how to do it.
I am pasting the code below.

Thanks so much

        var opt_params = { };
                opt_params[opensocial.DataRequest.PeopleRequestFields.MAX] = 
9999;
 
opt_params[opensocial.DataRequest.PeopleRequestFields.PROFILE_DETAILS]
= [
          opensocial.Person.Field.PROFILE_URL
        ];

 
req.add(req.newFetchPersonRequest(opensocial.DataRequest.PersonId.VIEWER,
opt_params), "viewer");
 
req.add(req.newFetchPeopleRequest(opensocial.DataRequest.Group.VIEWER_FRIENDS,

      function response(data) {
        var viewer = data.get("viewer").getData();
        var name = viewer.getDisplayName();
        var thumb =

        document.getElementById('main').innerHTML = html;
