It did indeed import

I do have one problem so far, and the is with the plugin / template edits.
From the posted example I am calling a variable: $mrwrb_forum_large
This does not seem to work, probably as I need to change it to {vb:raw mrwrb_forum_large} but that too seemingly does not work.
What else do I need to do to get this variable read / included into the template (it's coming from a plugin, but I do have one that reads from another template too)
