Ok here is what I want to do:
I have a sheet called 'Raw data' that has all my records in it. Then I have
three other sheets that each will be linked to 'raw data' but will only
contain specific records based on a field in 'Raw data'. For example raw
data sheet will look like this:

Name Type
john A
mike B
jerry C
Sarah --
Janet B

etc....

So I want sheet A to only give me the records that are Type 'A' (John in
this example)
I want sheet B to only give me the records that are Type 'B' (Mike & Janet
in this example)
I want sheet C to only give me the records that are Type 'C' (Jerry in this
example)

If a record in 'Raw data' sheet has neither A, B or C, then i don't want it
in any of my sheets.

How would I do this? Is it a Lookup or could I use an IF function?
