From what I can infer from my reading the function you shown here should
work.

As the example is not self-contained it is difficult to prove whether it is
indeed correct or not.  The error indicates that the statement "SELECT
valores.iva" was attempted somewhere but that exact construct is not presen=
t
in the function shown.  I am also not sure exactly where line "31" is in th=
e
supplied code.

I suggest two steps to move along further:

First, make sure that you are executing the function that you think you are=
.=20
Search path issues may have cropped up somewhere and a previous, invalid,
version may still be sitting around somewhere.

Next (if necessary), try to narrow down, keep, and point out only the
offending code and whatever is minimally necessary to make it execute.

Unless the example provided is self-contained simply putting out the entire
code without any commentary makes it more difficult for people to provide
help.

I see a UTF8 byte order mark (BOM) in front of "valores.iva" there,
which plpgsql is interpreting as part of the record name, so it doesn't
find any matching variable.  I'd be the first to agree that the error
message isn't too helpful.  But your text editor and your mailer didn't
do you any favors either, if they hid that BOM from you.
