As you can see find each cell in range R8:R1000 and the grab value in
column C
and put all duplicates in column s
for each P1 in the range the results are 2,4,5 for each duplicate.



c d ....... r s (results)
2 P1 2,4,5
3 P2 3
12 P5 12,13
13 P5 12,13
4 P1 2,4,5
5 P1 2,4,5
10 P22 10

Any help would be great!
