I am trying to summarise data I have in a table into months Jan,Feb,Mar etc, and need to separate the counts of various strings (such as HE(Technical)).
Some context: column "B" of my Data sheet are dates (not necessarily in chronological order), column "O" are keywords/strings.
I want to sort all instances of a particular string by the month based on the dates inputted in column "B".
May I know how I would go about this? My current formula (in title) only returns zeroes.
