In your original script you had a line "use strict;". Did you remove that line? It does seem that way, because otherwise the line "@fields = sort (@ElencoCampi);" would have given an error because you are using the global variable @fields instead of a local variable generated with my.

If you add a line "print \@fields;" to your loop you will see the problem, the reference never changes, it is always the same. But you need a new variable in every iteration of the loop so that they point to different memory locations

Change that line to "my @fields = sort (@ElencoCampi);" and your problem should go away.
