Reversing a Sketch with a button

Thanks for the advice. I added the missing line to the sketch and I cleaned up the "if" and "else" state but I got an error

Arduino: 1.5.6-r2 (Windows XP), Board: "Arduino Uno"

Street_lights_with_pot_switch:45: error: expected unqualified-id before 'else'
Street_lights_with_pot_switch:59: error: expected declaration before '}' token

What have I missed?
