Okay. On to page 14

I'm getting tired of asking questions. But thanks to everyone for your help. The rotate mode runs into the case structure and then connects to the symbol I can't seem to find. It's blue with an arrow and a box with a circle under it.
Also, do need to create a global variable called "header"? If so, what properties does it need to have?
And... what is connect to the PID on page 15?
Thanks again,
David
