Jquery sticky menu not being caught by footer

Question

Can anyone help me pinpoint the issue with my script please?

$(function () {
var top = $(\'#sidebar\').offset().top - parseFloat($(\'#sidebar\').css(\'marginTop\

Ok - many thanks @dark-ashelin

ended up with this - bit of a hack but it works.

$(function () {
var sidebar = $("#sidebar");
var top = $('#sidebar').offset().top - parseFloat($('#sidebar').css('marginTop').replace(/auto/, 0));
var footTop = $('#footer').offset().top - parseFloat($('#footer').css('marginTop').replace(/auto/, 0))-60;
var maxY = footTop - $('#sidebar').outerHeight() - 85;
$(window).scroll(function (evt) {
    var y = $(this).scrollTop();

    if (y > 100) {
        if (y < maxY) {
            $('#sidebar').addClass('stickyside').removeAttr('style');
        } else {
            $('#sidebar').removeClass('stickyside').css({
                position: 'absolute',
                top: (maxY + 50) + 'px'
            });
        }
    } else {
        $('#sidebar').removeClass('stickyside');
    }
});
});
