title: Zend GData Spreadsheet WorksheetID
body: <p>What is the <code>$worksheetId</code> from the Zend GData documentation supposed to be?</p>

  <pre><code>$query = new Zend_Gdata_Spreadsheets_ListQuery();
  $query-&gt;setSpreadsheetKey($spreadsheetKey);
  $query-&gt;setWorksheetId($worksheetId);
  $query-&gt;setSpreadsheetQuery('name=John and age&gt;25');
  $listFeed = $spreadsheetService-&gt;getListFeed($query);
  </code></pre>
  
  <p>The documentation uses that <code>$worksheetId</code> several times, but I can't seem to see where to get that from a spreadsheet.</p>
