                                                   'jquery.mousewheel.min.js',

                                                   'jquery.mCustomScrollbar.js',

                                                   'jquery-ui-1.8.21.custom.min.js',

                                                   'jquery-1.8.3.min.js',

                                                  ],complete: init});

          function init (){

                              sym.$("Fordnews").mCustomScrollbar({

                                        scrollInertia:500,

                                        scrollEasing:"easeOutCirc",

                                        scrollButtons:{

                                                  enable:true

                                                            }
