Update: I managed to figure out how to display the values as a “score”, by using: <?php echo GetWtiTotalCount($post->ID);?>
The only current issue is that the value isn’t updated via ajax, along with the other values. In other words, when a user submits a vote (like or dislike), that specific amount is updated and a text msg is displayed, however the GetWtiTotalCount value isn’t updated without refreshing the page.
