How do i target this 'h4' when it's parent is a 'var'

Hi there,

hoping you can help me here. it's a scroll-to and then highlight effect.
tutorial came from www.corydorning.com/blog/jquery-faqs-scroll-and-highlight-tutorial

i need to target an h4 inside the div we scroll to. the h4 is called :  h4.pink

here's the code.
  1. $(function() {
      $("#questions > li").click(function() {
        var qu = $(this).attr("id");
            var an = "#" + qu.replace("q","a");

            $.scrollTo(an, {duration: 800, axis:"y", onAfter:function(){
                $(an).effect("highlight", {color: "#ff33ff"}, 2000);
              }
            });
      });
        
        $(".return-top").click(function() {
            $.scrollTo("#topx", {duration: 800, axis:"y"});
        });
    });














i know the line we need to edit is:
  1.  $(an).effect("highlight", {color: "#ff33ff"}, 2000);
but don't know how to put "h4.pink" in there.. !?

any help much appreciated :)
