Unable to parse data from AJAX JSON

Actually in my website have a WebMethod that return two values from MySQL database.

I'm calling that method throw AJAX but the problem is that when i'm trying to parse a specific data i get the following error: Unexpected token o in JSON at position 1

Here is debug of ajax code enter image description here

While here is the code

function getAjax(data) {
    $.ajax({
        type: "POST",
        url: "stats.aspx/getSC",
        data: JSON.stringify({ data: data }),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (result) {
            var data = $.parseJSON(result);
            $('#sc-gg').text(data.TOTSC);
        },
        error: function (xhr) {
            alert(xhr.status);
        }
    });

}

The WebMethod will ever return just two values from the database which i will set to a "statistic box"
