I have a spreadsheet with baseball scores. I can't get my head around how to count individual series. Column L has most of what I need, but the games April 9 to 11 are series 1, games August 27 to 29 series 2, etc.
What sort of formula (helper columns are ok) would I need to look at cell L660, determine that its the same series as L661 and L662, but different than series in L780.
Thanks.
