Use SPL XLL to do this:

=spl("=p=(d=?1)(1).pselect@a(between(E(~),E(?2):E(?3))),d.to(2,).(~(p).sum())",B2:D6,G1,I1)


pselect()function gets positions of the eligible members. (N) represents the Nth member; it represents members at multiple positions when N is an integer sequence. to(2,) gets members from the 2nd to the last; ~ is the current member.
