datatable debugger code: ofehoc

The following page initializes the datatables, but I cannot select rows using the tableTools.
According to the debugger tableTools is not installed. Am I pointing to the incorrect cdn?

<!-- DataTables CSS -->
<link rel="stylesheet" type="text/css" href="//cdn.datatables.net/1.10.6/css/jquery.dataTables.min.css">
<!-- DataTables.tableTools CSS -->

<script type="text/javascript">

$(document).ready(function() {
    var table = $('#accounts_id').DataTable();
    var tt = new $.fn.dataTable.TableTools( table, {
        sRowSelect: 'single'
    } );
 
    $( tt.fnContainer() ).insertAfter('div.info');
} );

//-->
</script>

The table is referenced in this way:

<div class="info">
</div>
<h3>Accounts</h3>
<table id="accounts_id" class="display">

Resolved.
The problem was with the CDN. I must have copied it incorrectly.

<!-- tableTools -->
<script type="text/javascript" charset="utf8" src="//cdn.datatables.net/tabletools/2.2.4/js/dataTables.tableTools.min.js"></script>
