T-SQL Select Statement

A typical record in one of our database tables reads:

<field1>: Joe Bloggs
<field2>: 06/12/2007
<field3>: ko
<field4>: sales
<field5>: Microsoft Corporation
<field6>: Bill Gates

In this table there will be multiple records for Joe Bloggs each with different data in the rest of the fields; I am trying to bring back one record for each different name in <field1> where the date in <field2> is the maximum date from each set of records matching the name.  By using the code attached I can achieve this but if I try to add <field5> and <field6> to the script it shows all records containing Joe Bloggs that match the criteria, not just the one I previously got.

Does any of this make sense?  If so can someone please help!

Thanks

Danny
