[Koha] Help with ExportWithCsvProfile

I created a CSV Profile (that obviously isn't right) http://screencast.com/t/49bnF9SY1 , named it 'checkouts, and then set the ExportWithCsvProfile preference to 'checkouts'. When I exported I got a blank CSV file. Can someone tell me how to use this preference to get a list of the patron's checkouts as a CSV file? I will share your example in the manual. Thanks Nicole
