Magnetic Switch Arduino Code Help

[BuffNav]

I was wondering if someone could look at my code I'm new at this.  I have a 3 position JFS Switch that is wired to an arduino board.  Then I have a 12v magnet powered by a MOSFET board that is getting a signal from the Arduino board based on the JFS Switch position.  Ok so I'm able to get the switch to magnetically release when the JFS Run light goes out but I can't get the switch to hold unless I delete the JFS Run Light code.  Can someone help me find out where I messed up in the code so that when I flip the switch to either JFS start 1 or 2 I get a signal to the MOSFET for the magnetic to get power and then release the magnetic when the run light goes out.  Thanks!
