If you select Italy, the system displays suggestions in the city and county fields and you must use a proposed result. If you select a country other than Italy you can freely enter the data.

If you select Italy, the items must be selected from the list. Do not enter the data manually.

Simply type the first few letters and the list of suggested entries will appear. For example, if you want to indicate the city of Rome, just type in the City field "Rom" and then select the entry Roma Capitale. If you leave only "Rome", the system will produce an error.

Or if you want to indicate the city of San Donato Milanese, just select the suggested entry

If you type "S. Donato Milanese" the system will produce an error.
