[jQuery] My effects aren't working.

[Kyle]

    $("#emailForm").ajaxForm({
     target: "#formReturnArea",
     success: function(){
      $("#formHelp").fadeOut("slow");
      $('#formReturnArea').fadeIn("slow");
      $("input").attr("disabled", true);
      $("textarea").attr("disabled", true);
     }
    });

is in a separate javascript file, and when the form successful sends,
the help just disappears and the returnarea appears. But no effects,
and when i try throwing in timer events or an animate effect to delay
it, they do nothing.
