In order to avoid using offset function in determining the excel range to use in data validation (=OFFSET(C9,MATCH($B$6,$B$10:$B$22,0),0,COUNTIF(B10:B22,$B$6),1). Thanks Chandoo.org for this formula), I made this formula (=INDEX($C$10:$C$22,MATCH(B6,B10:B22,0)):INDEX(C10:C22,MATCH(2,1/(B10:B22=B6)))) which calculates the range correctly but is not accepted in data validation.
1). Any ideas on the way to determine the range without using offset function?
2). Any ideas of my formula above? Thanks
