  3. Hi, i have used INDEX() to rank a table of string information.
    What i would like to do is show only the last 3 inputs to each client.
    some clients have 6 inputs some 30, so my end result would be Client 1 shows RANK 4, 5 & 6 while Client 2 shows RANK 28, 29 & 30

    I cant seem to get a TOP filter and also this is 2 tables in an Access database connected by a Primary Key and Secondary Key.

    Please help?
