Good day, thanks for giving it a look.
SUMIF REVISED.png
The image explains better than I can describe in words.
The task is: I want the sum of credits that correspond to the course type.
I have tried using it on a single table and it worked fine, but it seems to have trouble with custom tables that has complex separation.
May I request any pieces of advise on the problem? I have attempted SUMPRODUCT and am currently thinking of SUMIF with VLOOKUP, but it seems difficult to implement.
