Jbeam Problem

I've been following the "Introduction to Vehicle Creation" wiki page and i have finally gotten to the part where you load the car into the game and view the jbeam structure upon hitting 'K'. For some reason the jbeam of my vehicle doesn't show up, and I feel like the problem is how the nodes & beams are pasted into my main file, but I am clueless on how to make it work (see attached image). Any help on this would be appreciated.
