[scroll up and down to find search terms]

Hi all. I've been long looking into a solution to my jQuery/JS code, but to no avail. I want to be able to scroll to the searched term when I type it in. It will do this now, but then if I search for a word that's at the top, I don't have anything for it to scroll up to it. Here is my code:

$(function() {
    $('.searchTerm').bind('keyup change', function(ev) {
        // pull in the new value
        var searchTerm = $(this).val();

        // remove any old highlighted terms
        $('body').removeHighlight();

        // disable highlighting if empty
        if ( searchTerm ) {
            // highlight the new term
            $('body').highlight( searchTerm );
        
            $('html, body').delay(1500).animate({
        scrollTop: $('#results').offset().top
    }, 475);
        }
    });
});

Is there something missing, or am I using the wrong code? I don't know what to do.
