Add BP Group Hierarchy to Custom Buddypress Theme

I have purchased a popular custom buddypress theme called Salutation. ([login to view URL]) I want to install a plugin. [login to view URL] I have tried this on my site and the plugin will only work on the Buddypress default template/theme, it will not work on the Salutation theme. I have found instructions below on how this can be done. [login to view URL] I want someone to make the modifications required to make this plugin work as it is essential for my site. It seems simple but is beyond my current skills.
