自动保存不起作用

Can anyone see an obvious reason why this AutoSave is not working? I set alerts and it works until it hits the $.ajax call

var timer;
$('#about').keyup(function () {
clearTimeout(timer);
timer = setTimeout(function (event) {

    var aboutVal = $('#about').val();
    var memberID = $('#memberID').val();

    $.ajax({
        url: 'includes/auto-save-about.asp',
        data: 'aboutVal='+aboutVal+'&memberID='+memberID,
        success: function(data) {
            $("#aboutStatus").html('Saved').show().fadeOut(3000);
        }
    });

}, 2000);
});
