Read about $Field here System fields. These are basically system generated fields which include information related to the meta data associated with your app. $Field include the name of all the fields in your app.

I think the current syntax would be this if($Field = 'Country', Sum(Sales)). It means that perform sum of sales only when a user has selected Country in $Field list box.
