What's the error message?????

Hi there!

On my view I have this:

@foreach($get_tracker_data as $get_tracker_data)
                                    <tr>
                                        <td><?php echo $get_tracker_data->neighbourhood;?></td>
                                        <td><?php echo $get_tracker_data->agent_first_name.' '.$get_tracker_data->agent_last_name;?></td>
                                        <td><?php echo $get_tracker_data->add_date;?></td>
                                    </tr>
@endforeach

And I'm getting the error: "Trying to get property of non-object" on the first line in php where I echo.

I did this EXACT same process on another function and view and it worked fine. Thanks.
