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_fields_form_submit($form, &$form_state) {
  $edit = $form_state['values'];
  $form_values = array();
  foreach ($edit as $delta => $value) {

    // If this is some form item we don't care about, skip it.
    if (!is_array($value) || !is_numeric($delta)) {
      continue;
    }
    $value['calc'] = trim($value['calc']);
    if (empty($value['calc'])) {

      // remove blank fields, don't save them
