function change_column3_content($input, $input_info, $field, $text, $value, $form_id) {
    // build field name, must match List field syntax to be processed correctly
    $input_field_name = 'input_' . $field->id . '[]';
    $new_input = '<textarea name="' . $input_field_name . '" class="textarea medium" cols="50" rows="10">' . $value . '</textarea>';
