[jQuery] Help Add variable to jquery file tree

[262Rui]

I'm using jquery file tree plugin and my document head goes like this:

<script type="text/javascript">
                        $(document).ready( function() {
                                $('#fileTreeDemo_3').fileTree({ root: 
'download/', script:
'conector.php' }, function(file) {
                                        alert('right click and save as...');
                                });
                        });
                </script>


On my html i have a table that contains the folowing

 <td id="cbfv_55" class="fieldCell">.....</td>

Now I want to have a variable instead of (root: 'download/') i would
like to pass the value that comes from
 $("td #cbfv_55").text();

Is this possible?? how can this be achieved.
