Hello, I have a question.

I am analyzing scores for 2 semesters, and I am trying to alternate between semester 1,2 and final scores. How do I go about index and match with a slicer for Sem 1,2 and final scores, and ensure the grade shown correctly matches the student's registration number? My formula is =INDEX(INDEX(Rawdata[#All],0,(MATCH($F$2,Rawdata[#Headers],0))),MATCH(C5,Rawdata[REG. F22/])) for the final grade but it gives the grade of the wrong student. (*highlighted in yellow)

I have attached a copy of my Excel 2016 workbook above.

I appreciate your help. Thank you.
