I think you want:
select into NEW.field2 function_that_returns_int(NEW.field1);

or even:
NEW.field2 := function_that_returns_int(NEW.field1);

Works for me ...

create table fooey (q1 int, q2 int);

create function myt() returns trigger language plpgsql as $$
begin
select abs(new.q1) into new.q2;
return new;
end$$;

create trigger mytrig before insert on fooey for each row
execute procedure myt();

insert into fooey values(-42, 77);

select * from fooey;
q1 | q2
-----+----
-42 | 42
(1 row)

Perhaps you should show a full example of what you're doing.

sorry for the late update
thank you all,
I found the cause, that specific sentence was correct, it was in another
sentence of the same function, I think it was late at night and I was tired.

thank you anyway

best regards
