Question

I am getting this Uncaught SyntaxError: Unexpected identifier error , Why ?
I think i have used the syntax properly ?

$.ajax({
    url: "loadcontent1.php",
    data: {
        lastid: '$(".postitem").size()',
        location: '$("#location").val()',
        rstatus: '$("#rstatus").val()',
        gender: '$("#gender").val()'
    }
    success: function(html) {
        Uncaught SyntaxError: Unexpected identifier
        if (html) {
            $("#contentwrapper").append(html);
            $('div#ajaxloader').hide();

            $("#contentwrapper").masonry('reload');
            FB.XFBML.parse();

        } else {
            $('div#ajaxloader').html('<center>No more Images.</center>');
        }

    }
});​

You left off the comma after the data

$.ajax({
    url: "loadcontent1.php",
    data: {
        lastid: $(".postitem").size(),
        location: $("#location").val(),
        rstatus: $("#rstatus").val(),
        gender: $("#gender").val() // not strings!
    }//, comma here!
    success: function(html) {
