I'm not sure you do understand with P() and E() are used for. When you say you want the included or excluded values...of what? For what reason?
You can use the expressions provided by everyone here to pull any name where they have a value for year 2011, but is that what you want? Is it the name of those with sales in 2011 or is it any sales in 2011? There you're best using straight set analysis.
As sunny said, be more explicit about what you want because at the minute it doesn't make much sense..!
