=SUMPRODUCT(arrayformula(COUNTIFS(
'All'!$B$2:$B, SPLIT(HLOOKUP(A18,'Funnel'!$A$1:$D$4,4,FALSE),"|"),
DAY('All'!$C$12:$C), DAY(C13),
MONTH('All'!$C$12:$C), MONTH(C13),
YEAR('All'!$C$12:$C), YEAR(C13),
'All'!H:H, A12)))
This formula returns an "array arguments to countif are of different size" error how do I fix it I have already added arrayformula but still it doesn't work
the error-code of different size
itself is self-explanatory. your criteria_range
Column_B starts at row_2; date Column_C starts at row_12; Column_H starts at row_1
