SUMIFS: If no criteria match, leave cell blank, else return value

Here is a potentially easier solution, where everything in [] gets replaced by your specific ranges and criteria cell names:

=IF(COUNTIF([criteria range], [criteria])>0, SUMIFS([sum range], [criteria range], [criteria]), "")

example: =IF(COUNTIF(H:H, A2)>0, SUMIFS(I:I, H:H, A2), "")

This will give you back a blank whenever there isn't a data match to sum, and will help you avoid false zeros.

The logic here is IF count finds at least one match, THEN add up the items with a match, ELSE return a blank.
