Editing bp_activity_action

http://s1314.photobucket.com/user/Corbin1988/media/Topics_zps3f2fb70a.jpg.html?sort=3&o=0

I'm trying to edit the header area where it says:

kyle started the topic Hi in the forum Group Forums 3 weeks, 2 days ago

I would basically just like it to be the topic name.

The code exists in wp-content/themes/mychildtheme/activity/ entry.php

Line 29

<div class="activity-header">

<?php bp_activity_action(); ?>

</div>

Can you please help me :slight_smile:

Parent Theme: bp-default
