Index Match Error

The language is throwing me off somewhat, but I think the error is coming from the MATCH(?) part.

The syntax for MATCH is...
=MATCH(search-criteria, criteria-range (MUST be 1 single column), 0) Use 0 if you want an exact match

looking at that part of your formula...
=MINDSTE(HVIS(W11Tabel1[Shortlisted]="Yes";RÆKKE(Tabel1[Code])-RÆKKE($A$4);"");RÆKKER($1:1))

(search criteria) It looks like you are searching for YES

Criteria range) looks like you have 2 ranges there? ...RÆKKE(Tabel1[Code])-RÆKKE($A$4);"")...I doubt that part is correct?

Then you are setting up a sequence of numbers...RÆKKER($1:1))
I suspect that is meant yo be the "column" to use? If so, your ) are in the wrong place

All of that is just pure guessing, upload a small (clean) sample workbook (not a pic) of what you are working with, and what your expected outcome would look like, and we can tell better what you are trying to do
