AutoComplete loading XML source Not Working

AutoComplete loading XML source Not Working

Hi all and thanks in advance!! Kinda of a Newbie with JavaScript... I had this script working on another server with another xml source but can seem to get this working. What I've done is added 2 more columns to my Data source (XML) as I'm wanting to use the same source on 3 pages just with slightly different outputs.
1. A jQuery search Suggest/Autocomplete
2. A jQuery A to Z list
3. A jQuery Department/Speciality list.

Ok the first problem seems to that my data source has 2 more sections in it and nothing seems to be reading on the Autocomplete?? I think the issue is in the finding the new rows...? Please Help.

XML Code:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<keywords xmlns:xsi="">
<label>A to Z</label>
<label>Acute Medicine</label>
<label>Acute Vertigo</label>

HTML Code:

<div id="gray">
<h2>Looking for something on the Emergency intranet....</h2>
<form name="s-search" action="">
<label for="searchBox">Keyword Search:</label>
<input name="query" type="text" id="searchBox" class="keysearch"/>  
<input id="submitbut" type="submit" value="Submit »">   
<a href="departments-a-z.htm">Or search using the A to Z list</a></form><br></div>

And the JavaScript:

<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript" src="jquery.compact.js"></script>

<script type="text/javascript">
var myArr = [];
   type: "GET",
   url: "includes/keywords.xml", // change to full path of file on server also.  The location for the Microsoft Excel file is at N:\Publishing\xml-data-backup/default-keywords-new.xls while in the development stage before live.  Add the content to the Excel document in alphabetical order then export to xml.
   dataType: "xml",
   success:  function(xml) {
   $('key',xml).each(function() {
            var row ={};
            row.label = $(this).find("label").text();
            row.url = $(this).find("url").text();
   complete: setupAC,
   error: function() {
      alert("XML File could not be found");

 function setupAC() {
   source: myArr,
   minLength: 0,
   select: function(event,ui){

UPDATE: I've updated the format for easier reading (kindly mentioned by watusiware below) and also will add a NOTE that the version of jQuery is not by choice as I'm in a locked down environment and don't control that and they won't update. So I have to work with what I've got, but as mentioned I had this working on another departments site so in theory it should also work???
