That's how I knew there were instructions here somewhere, because I remembered you talking about it before.
What happened was, I added the chunk for the dial into Dials.cfg and then forgot about increasing the number of dials in the Dials=xx at the top. Then I remembered and went back to look at it and it said Dials=72 and I knew the one I added was Dial72 so I thought it was fine. And then I remembered that the dials started with Dial0 so adding Dial72 made it 73 dials, not 72 dials.

I am so smart! S-M-R-T SMART!
Anyway I fixed that and went back in and it's there in the right place and the helm responds when I click it and that was as far as I got because it was bedtime but it seems like that would be all there is to it so I think I'm good.
