I have the following array formula that works correctly as long as the range
I16:I39 has data in it; however there may be times when cells in that range are set to blank via another formula. When this happens, I get an error.

=SUM((E16:E39>TODAY()-180)*(E16:E39<=TODAY())*(I16:I39<>"")*(I16:I39))*8
Thanks.
