FYI, If you have blank cells or zero in a date column & corresponding column has numbers MONTH function will sum those numbers if the Month in A1 is 1. because in excel blank & zeros consider as Jan (in month case) To avoid this this need to use a another condition like (Sheet1!A2:A200<>"") or use TEXT function like,
=SUMPRODUCT((TEXT(Sheet1!A$2:A$200,"m;;;")=A1&"")+0,Sheet1!B$2:B$200) Where A1 is month like 1, 2, 3, 4, 5, etc,... If you want to use month like Jan, Feb, Mar in A1, change "m;;;" to "mmm;;;" (3 m's) If you want to use full month like January, February. use 4 m's ___________ HTH, Haseeb -- FORUM RULES (986+ members already BANNED for violation) 1) Use concise, accurate thread titles.
