Hi Salvatore,

I've imported your csv file, copied the features to a new scratch memory
layer, and created a new field named 'zona_fill2' using the Field Calculator
with the following expression:

if( "zona" is empty,  attribute(  get_feature_by_id(@layer, $id -1),
'zona_fill2') , "zona")

and it seems to me the above expression populates the "zona_fill2" field in
the same way the "zona_fill1" was populated.

Best regards.

Andrea
