Continuing from the comments: You seem to be a little obsessed with callbacks, when you don't seem to need any! :)

The simple change to your existing code is to throw away cnf and simply put your code in the success part of the ajax call:

$("#form").submit(function (e) {
    $.ajax({
        type: "POST",
        url: 'page.php',
        data: $('#form').serialize(),
        async: true,
        success: function (responseText) {
            if (responseText.indexOf('err') != -1) {
                // Do something when it fails here
            } else {
                // Do something when it succeeds here!!!!
                alert('ok');
                // e.g. move on to "step 2"
            }
        },
        error: function () {
           // Do something when it fails here
        }
    });
});
