Sorting Multiple Columns Alphabetically

How do I sort multiple columns alphabetically with the last name first, then the first name as the 2nd sorting option?

Here is an example of what I have:

year; first; last
2011 chrisBell
2010 chrisBell
2009 chrisBell
2008 chrisBell

[Code] .......

As you can see, the first names aren't sorted 100% alphabetically. I think issue stems from the years 2001 n-2006 n. I have to use the 2001 n since its a different data than the normal 2001.

The default sorting was by year:
2012
2011
2010
2009

[Code] .......

So I want it to sort by last first, then first name. Then it should sort by the default sort I already had in the left column (years).
