I have been working on this code for my website's news feed for a while now. I have the site setup where members can comment on comments. Currently the news feed shows all comments members post on "main" comments.
I want to only show the most recent sub comment. The area of the code where I am currently trying to get this working is "location_comments" and "location_comments_b".
Here is my complete code for recent post aka news feed. It currently works but shows all "location_comments_b".
