How to use the fare spreadsheet?
 

I download the spreadsheet, but then I can't get it to do anything. It seems to show D fares in US dollars, but if I change the fare class or the currency, nothing happens. I must be missing something. Can anyone help?
Also, I seem to remember that Gibraltar was much cheaper than EU countries, but for DONE3 it seems to be only about 7% cheaper. Does that sound right?

Check to see if it's set on manual recalculation instead of automatic (Tools/Options/Calculation.) Otherwise you can calculate manually by hitting F9.

GIB used to be cheap but that changed a year or two ago.

Thanks Gardyloo, worked like a charm.
