Uncaught ReferenceError: ntb_scr_js is not defined

The code is:

!function(a)
{
function b(b,c,d){b.bind("marquee",
function(b,e){var f=a(this),g=parseInt(f.parent().width()),h=parseInt(f.width()),i=parseInt(f.position().left),
j=c;switch(d){case"right":"undefined"==typeof e?(f.css({left:g}),g=-h):g=i-(h+g);break;
default:"undefined"==typeof e?f.css({left:-h}):g+=i+h}f.animate({left:g},{duration:j,easing:"linear",
complete:function(){f.trigger("marquee")},
step:function(){"right"==d?parseInt(f.position().left)<-parseInt(f.width())&&(f.stop(),
f.trigger("marquee")):parseInt(f.position().left)>parseInt(f.parent().width())&&(f.stop(),
f.trigger("marquee"))}})}).trigger("marquee");
var e=ntb_scr_js.mouse;1==e&&(b.mouseover(function(){a(this).stop()}),
b.mouseout(function(){a(this).trigger("marquee",["resume"])}))
}
var c=a("#scroll-ntb-elem"),d=4e3*ntb_scr_js.speed_scr,e=ntb_scr_js.ori_scr;b(c,d,e)
}(jQuery);
