Query assistance

I am trying to pull some "notes" from a sql database....the notes that
are put into the database come via the web and the user is entering it
for a certain task. they are stored in their own table and field and
get assigned and incremental ID #.

I want to be able to pull up the latest entry to the task, not all of
the notes just the latest one.. The entry does get a timestamp in the
field so I am thinking I might be able to look at that field
somehow... Right now my query shows all notes / entries for the task.

I am an intermediate sql query guy so I hopefully expained enough to
get assistance.

Let me know if you need to know more.Here is the sample data...
iwmsjn_Note iwmsjn_Timestamp
working on SQL queries for reports2/17/2006 4:20:34 PM
Researching a report for Sheri 2/28/2006 4:35:21 PM
Working on Reports / Queries 3/3/2006 3:34:04 PM
Test Delete 3/8/2006 1:45:30 PM

I only want the one that says "Test Delete" stamped for TODAY...not
the others.|||This should do it...

selectiwmsjn_Note
from[tablename] a
whereiwmsjn_Timestamp = (select max(iwmsjn_Timestamp)
from [tablename] b
where a.[ID] = b.[ID])
