If I have some data in my worksheet, with headers, with four columns, set out below:

A - Date.......-Date
B - Name.......-Text
C - Category...- Text
D - Value......- Currency

I want to sort it by date, how what would I need to put in the sort function, and how would I go about selecting the range? Could I just select the columns?

Sorry if this is a bit basic, but the help isn't very clear
Thanks.
