Maybe somebody can help me:
Firstly i need to check which letter is in Column range A4:A200.
and THEN, IF it is letter B or C or M or Y . sum numbers in column B for letter in column A.
Like in attached you see example :
it will be A4 and A8 “b” letter sum = 2
After that when i will have usage sum of every letter i need to minus it from sum of “K” column same letter.
Thanks
