Sum of people that has attended a week of seminars hosted by specific lecturers
Hi Forum,

In the below spreadsheet I'd like to know how many Pax each Person has had on their seminars these 5 days.  I've tried to use VLOOKUP but that only works for days when each lecturer only did 1 seminare.  Lecturers never do more than 2 seminars in a day.  I've experimented with ARRAYFORMULA, SUM and VLOOKUP and failed miserably...  I have a feeling there is an easier solution since this isn't exactly a very strange situation...

I'd like to have a resulting list like this:
Kind regards,
Matthias
