I am working on a school rooming timetable system. I am finding a formula which finds if a particular room is used during a specific period by which class and teacher.
There is a staff overview with clean data of which class and room they are in, alongside preferred results.

For example, for on the overview, Monday Period 1 (Column B) Staff 1 uses room BG01 for the class 07MA01. Thus on the room overview, it shows that in Period 1, Staff 1 uses BG01 for 07MA01.
