Solved...

I changed the following line in module.attributes.php from

PHP Code:
<?php
  if ($options_comment[$i] != '' and $options_comment_position[$i] == '0') {
to

PHP Code:
<?php
  if ($options_comment[$i] != '1' and $options_comment_position[$i] == '0') {
This brings the comment box in whether or not a comment is present.

Thanks to all who assisted.
