Hello,
I'm trying to sum the values in a table based on several conditions being met and I'm having trouble getting the correct answer. The array formula in the attached file (see cell AA3) sums the values based upon the single condition that the hour is greater than or equal to 8. When I try to add the second condition using the AND formula, I'm getting #Value error (see cell AB3). The second condition is that Z3="On". Any help is greatly appreciated!
