Any thoughts on why I might be getting the following notification in Firebug when I try to run the RS?

TypeError: a.ev.on is not a function

this is the part of the code it refers me to:
(function(b){b.rsProto._j4=function(){var c,a=this;if({a.ev.on("rsBeforeMove",function(){b()});

    Thanks Dmitry. But I just figured it out and came back here to let you know. I was getting an older version of jquery (1.6.1). When I realized that and updated to the latest jquery, the slider started working .
    Nice product!!!
