Hi Fred,
Sorry...forgot to say "disregard the day in the month." Here's what I
came up with. It's a bit verbose but it's for clarity's sake:
FUNCTION CountMonths(tdStart as Date, tdEnd as Date) as Integer
LOCAL liNumMonths as Integer, liStartYear as Integer, liEndYear
as
Integer, liStartMonth as Integer, liEndMonth as Integer
IF tdEnd >= tdStart THEN
liStartYear = YEAR(tdStart)
liEndYear = YEAR(tdEnd)
liStartMonth = MONTH(tdStart)
liEndMonth = MONTH(tdEnd)
IF liStartMonth >= liEndMonth THEN && take 12 months
from year for
date math
liEndYear = liEndYear - 1
liEndMonth = liEndMonth + 12
ENDIF
liNumMonths = ((liEndYear - liStartYear) * 12) +
(liEndMonth -
liStartMonth) + 1 && last +1 is to include the month you're in
ELSE && invalid entry...start shouldn't be later than end
liNumMonths = -1
ENDIF && tdEnd >= tdStart
RETURN liNumMonths
ENDFUNC && CountMonths(tdStart as Date, tdEnd as Date) as Integer
