This module will allow you to add calculated fields to views tables and compute (SUM, COUNT, AVG, etc) columns of numeric data in a views table.

Code

function _views_calc_substitutions($base = 'node') {

  // We retrieve fields of type 'filter' instead of 'field'
  // because filters have the actual table columns we might
  // do calculations on, while fields may have only a nid.
  $fields = views_calc_views_fetch_fields($base, 'filter');
  $substitutions['node.nid'] = '%Node.nid';
  $substitutions['node.uid'] = '%Node.uid';
  foreach ($fields as $key => $field) {

    // For now, omit calculated fields from available fields list.
    // Doing caculations on calculated fields will require some
    // complex additional logic, especially if they are nested
    // several levels deep.
    if (substr($key, 0, 4) != '.cid') {
      $substitutions[$key] = '%' . str_replace(' ', '', $key);
    }
  }
  return $substitutions;
}
