I have this formula which makes NX16 and NX17 have a value of 0.5 rather 1. I need to expand this to make NX14 and NX15 to also have a value of 0.5 but am stuck =SUMPRODUCT((OFFSET($A8,0,31*($A$3-1)+1,1,31)<>"")*(IF(OFFSET($A8,0,31*($A$3-1)+1,1,31)=$NX$16,0.5,IF(OFFSET($A8,0,31*($A$3-1)+1,1,31)=$NX$17,0.5,1))*(OFFSET($A$4,0,31*($A$3-1)+1,1,31))))
