So I'm trying to use the following formula to check if either of 2 cells in a column is blank and if neither if blank that return the number of days between them and if either is blank to return an empty cell:
={"Consultant Turn Around";ArrayFormula(IF(OR(ISBLANK(J2:J),ISBLANK(K2:K))),,NETWORKDAYS(J2:J,K2:K,Data!B2:B))}
However I'm getting the error:
Wrong number of arguments to ARRAYFORMULA. Expected 1 arguments, but got 3 arguments.
and I can't for the life of me figure out what I'm doing wrong. I think its something with how the OR statement works since I have a very similar formula that only checks one cell that works fine.
