I'm having trouble working midnight into this equation. I need it to be 'AM', but the way I have it written, midnight will be 'PM' and noon will be 'AM' if the iStartingAM is set to TRUE. Just the reverse of what I need. The scenario won't come up often, if ever, but I have to account for the possibility. These statements are in loops (iHour changes value), and there is more code inbetween, but but this should be enough to get the gist of it.

iHour = 24
m.StartingAM = .T.

REPLACE AppointmentTypeSetsEdit.DisplayTime WITH PADL(AppointmentTypeSetsEdit.Hour, 2, '0') ;
     + ':' + '00' + ' ' ;
     + IIF(iHour>=12 AND iHour<=24,IIF(m.StartingAM,'PM','AM'),'AM')

REPLACE AppointmentTypeSetsEdit.DisplayTime WITH PADL(AppointmentTypeSetsEdit.Hour, 2,'0') ;
     + ':' + PADL(AppointmentTypeSetsEdit.Minute, 2, '0') + ' ' ;
     + IIF(iHour>=12 AND iHour<=24,IIF(m.StartingAM,'PM','AM'),'AM')

Partial results...
