I have changed the formula according to my worksheet but it only gives me
N/A...

I have my names/room mates in the columns of B and Q, and my Excel uses the
; instead of commas to separate in formulas. Could you please look through it
for me? Have I done wrong ...?

My first row is #3.

=IF(INDEX($B$3:$B$100;MATCH(Q3;$B$3:$B$100;0))=Q3; "Match";"No match")

In column A I have the names of the participants and in column B I have the

columns of course. Now I need to check that if John is Kenns room mate then
Kenn is also Johns room mate.

Could anyone please help me.

Thanks,

In column C (C2)
=IF(INDEX($A$2:$A$100,MATCH(B2,$A$2:$A$100,0))=B2, "Match","No match")

You can then use filter on C or simply spot inconsistencies.
