Yep that's where I'm stuck too. I even asked DH as some people in the hint forum said they did that but no luck.
Lol! I did exactly the same thing tonight. He was totally useless I've been googling all sorts of combinations to try to find this illusive connection between them. I found two things that were possibilities, but I still have no idea what the missing thing is. I've just been putting hundreds of random things in the address bar, lol
