How do I save sort settings in Excel 2007
 

In Excel 2007 I have a list that I sort by 3 levels. How can I get excel to
remember the sort order I want to use. Sometimes it remembers breifly but
not for long and I have to go through the process of setting the levels. In
my case I want to sort by date, name & dollar amount. If I make changes and
hit sort again in most cases I have to re-enter the sort levels
