New Comment Activity - Adding The Content

Hello Everyone,

I stumbled across this post here - and it resolved the first thing I was looking to do but I am having trouble getting the commented activity to display the actual post along with the new comment update in the activity stream. Has anyone successfully done this? Is there anything you would like to add to the code in the link? I’ve added a function and then I updated the template file as indicated. What am I missing?

Thanks in advance for any help that can be offered!
