After ajax load(), new content is not available to grab.

After ajax load(), new content is not available to grab.

I am using the load() method to load navigation sections of hidden copy, which I will later grab and display.  After the hidden copy loads, I am grabbing selected divs, and bringing them into an area where the copy will be displayed.  My problem is that after I load the new copy, replacing the old copy, and I go to retrieve it, it gives me the old copy still (eventhough firebug shows me that the load() actually did bring in and replace the copy...so it's grabbing and displaying copy not even in the file anymore!)  Why is this happening?  the code is below.

$(document).ready(function() {
    $('#showcase_holder ul li:first').addClass("in_view");
    
    $('#project_navigation ul li a').click(function(){
url = $(this).attr("href");
$('#project_subnavigation ul').hide().load(url + " #project_subnavigation ", function() {
        $('#project_subnavigation ul').fadeIn(400);
              });
        $('#holder').hide().load(url + " #holder p", function() {
        $('#holder').fadeIn(400);
              });
        $('#content_holder').load(url + " #inner_holder");

        $('.current').removeClass("current");
        $(this).addClass("current");//"current" navigation
        return false;
});
    
    
        
    $(document).delegate('#project_subnavigation ul li a', 'click', function(){
        section = $(this).attr("rel");
        new_image = '../images/port/' + section + '.jpg';
        $('#showcase_holder ul').append('<li><img src="' + new_image + '" /></li>').
        animate({left: '-=618'}, 500);
        $('#active_copy p').fadeOut(200);
        $('#holder').load('#content_holder #' + section + ' p');
        $('#active_copy p').fadeIn(200);
        return false;
    });


    changeCopy = function(){
        $('#active_copy p').fadeOut(200);
        $('#holder').load('#content_holder #' + section + ' p');
        $('#active_copy p').fadeIn(200);
    };

});
