Form Select Menu and include page upon selection help!!

This works perfectly in Firefox and Safari but in both IE 6 and 7 I
cannot get my includes to display... any suggestions? I have not found
any better solutions to accomplish using a drop down menu to display
an html message.

<script type="text/javascript">
        var message = new Array();
        message[1] = "<!-- #include file ="global/include-test.asp" -->";
        message[2] = "You have selected the second item";
        message[3] = "You have selected the last item";

        $(document).ready(function(){
                $("#message_display2").html("<!-- #include file ="global/include-
test.asp" -->");

                $("#item_select").change(function()
                {
                        var message_index

                        message_index = $("#item_select").val();
                        $("#message_display").empty();

                        if (message_index > 0)
                                $("#message_display").append(message[message_index]);
                });
        });
        </script>

<select name="select" id="item_select">
  <option value="1">Item 1</option>
  <option value="2" >Item 2</option>
  <option value="3">Item 3</option>
</select>
<div id="message_display"></div>
