Flip flop and reset

i am trying to do my first Pro-face job using it's internal logic. I'm trying to write some pump alternator logic that will set or reset a single output. i also want a manual button to toggle the lead/lag. we'll because of scanning i suppose my attached logic won't cut it. Any ideas?

DG,
Set up your alternator (flip-flop) like this. Then the ALTERNATION_OUTPUT will go on first time, then off the second time that either the HOUR_COUNTER is done, or the PUMP_ALTERNATE_PB is pressed.
