I'm not sure what you are asking for, but I suggest you start using Firebug to catch errors and debug your code better. Suppose your code is complete, then you have a lot of errors (brackets..etc) I suggest using netbeans (for example) and not a notepad:

var total = parseInt($("div.total-text").text().substring(1), 10);
$("input[name='rmr']").bind('change', function () {
    var amount = 0;
    switch (this.value) {
    case "1":
        amount = 3;
        break;
    case "2":
        amount = 5.5;
        break;
    case "4":
        amount = 10;
        break;
    }
    $("div.total-text").text("£" + (total + amount));
});
$(document).ready(function () {
    $('#primary').bind('change', function () {
        $.ajax({
            type: "POST",
            url: "include/unlock_function.php",
            data: $(this).is(':checked'),
            success: function (theresponse) {}
        });
    });
});

Example for the rmr radio.
