title: SPServices GetListItems lookup field not retrieved
body: <p>With a MOSS 2007 Custom List <br />
  having a field that is a lookup type into another Custom List at the same site, <br />
  using the following fails to bring in the lookup field, <br />
  though the other (non-lookup) fields <i>are</i> present in the results</p>
  
  <pre><code>$().SPServices({
      operation: "GetListItems",
      async: false,
  CAMLViewFields: "&lt;ViewFields&gt;" 
                + " &lt;FieldRef Name='Title' /&gt;  " 
                + " &lt;FieldRef Name='Dt_x0020_Sec_x0020_Lev' /&gt;" 
                + "&lt;/ViewFields&gt; ",
        listName: "Media Inventory",
        completefunc: Get_MI_Completed
      });
  </code></pre>
  
  <p>The Single Line of Text fields, Date/Time fields, etc. are present in the response, <br />
  but not the Lookup field which is a single line of text.</p>
  
  <p>The list referenced in GetListItems has 285 entries, <br />
  the looked-up value comes from a list with 126 entries.</p>
