I am trying to use this array formula

=SUM(N(OFFSET(INDEX(Sheet1!$C$12:$H$16,0,MATCH(MIN ($B2,3)&$C2,{"1E","2E","3E","1O","2O","3O"},0)),MA TCH(MID($D2,ROW(INDIRECT("1:"&LEN($D2))),1),Sheet1 !$B$12:$B$16,0)-1,0)))

I have tried your solution but does not seem to work.

Depends what you want to do, but here's one approach:

=IF(X1="",0,array_formula)

commit with CTRL-SHIFT-ENTER.

However, if you want an alternative non-array solution to your earlier
post, check out my answer.

Hope this helps.
