Hi. I'm fairly new to javaScript and jQuery, so hopefully this will be a quick fix. I need to display a table containing data that can be grouped into several categories, and I'd like to implement a slideToggle that hides/reveals all of the observations in each given category.

The code below should (ideally) display a table with 4 columns and 9 rows, with every group of 3 rows preceded by a green "Section i" row. I would like each Section header to work as a slideToggle that expands or collapses all of the rows beneath it. Right now, nothing is collapsing. Any thoughts?

<head>
  <style type="text/css">
    td{padding:5px;}
  </style>

  <script type="text/javascript" src="js/jquery.js"></script>
  <script type="text/javascript"> 
      $(document).ready(function(){
      $(".flip").click(function(){
          $(this).next(".section").slideToggle();
      });
  });
  </script>

</head>

<body>
    <p>
        <table id="main_table">
        <thead>
            <tr class="firstline">
                <th>Column1</th>
                <th>Column2</th>
                <th>Column3</th>
                <th>Column4</th>
            </tr>
        </thead>
        <tbody>
            <tr style="background-color:green; color:white"> 
                <td  colspan="4" class="flip"> Section 1 </td> 
            </tr>
            <div class="section">
            <tr>
                <td>item 111</td>
                <td>item 112</td>
                <td>item 113</td>
                <td>item 114</td>
            </tr>
            <tr>
