                                array('controller' => 'units',
'action' => 'getUnits', $unit['Unit']['id']),
                                array('update' => 'builder', 'escape'

{
                                                        for(var i=0; i
< document.build_form.elements.length;i++){
                                                                if
(document.build_form.elements[i].name.substr(0,4) == "note"){
 
notes.push(document.build_form.elements[i].value);
                                                                }
                                                        }
                                                }
                                                notes.reverse();
                                                nums.reverse();
                                        '));
