I do have a table presented as above.
On column "A" a range of daily date with the format: dd/mm/yy.
On column "B" a range of values.
what I want to do is to make a sum of values in column "B" conditionally on the month in column "A".
a example, for the month of January (01) it will be 14 (5+9), for the month of February (02), 10 (8+2).
The outcome must be a table with 2 columns :
One with the months (January, February, March...)
One with the corresponding sum (14, 10, 7...)
I was thinking about the use of a dictionary...
Any help would be so nice of you.
Thank you
