Hi nedash,

Use like below.

if (!repeat)
    $this.parent().find('li:nth-child(' + current + ') a').stop(true, true).animate({ 'marginRight': '-20px' }, 300, function () {
        $(this).animate({ 'opacity': '0.7' }, 700);
        $(this).css("background-color", "#FF0094");
        $(this).css("font-weight", "bold")
    });

current = parseInt($this.index() + 1);

var elem = $('a', $this);

elem.stop(true, true).animate({ 'marginRight': '0px', 'opacity': '1.0' }, 300).css("background-color", "#FF0094").css("font-weight", "bold");
