I am looking to add the total hotel night stays from multiple labels in a single criteria column. This is my formula, but it results in "0" which is incorrect:
=SUMIFS(NIGHTS10:NIGHTS38, AFFILIATION10:AFFILIATION38, "Researcher", AFFILIATION10:AFFILIATION38, "RAN", AFFILIATION10:AFFILIATION38, "ECD awardee")
NIGHTS:NIGHTS = # of hotel night stays
AFFILIATION:AFFILIATION = location of labels (criteria)
SUMIF or SUMIFS? What am I missing in the formula above if using SUMIFS?
