Formula column pl/sql

Question

I have a sql statement in the report builder with groups defined. The field in the last group contains text. I need to concatenate all values in the group. I was attempting to use a formula column. Could someone please send me an example of the pl/sql that would accomplish this?
Thanks
Ruth

function CF_ULTIMO_MESFormula return Char is
tipo varchar2(50);
tamanho number;
nome varchar2(22);
begin
begin
     begin
select to_char(dt_referencia, 'mm')
into tipo
from salario_base_mensal
where nu_codigo = :nu_codigo
and nu_versao = :nu_versao
and nu_empresa = :nu_empresa
and nu_filial = :nu_filial
and dt_referencia = (select max(dt_referencia)
from salario_base_mensal
where nu_codigo = :nu_codigo
and nu_versao = :nu_versao
and nu_empresa = :nu_empresa
and nu_filial = :nu_filial);
exception
when others then
     tipo := null;
     return (tipo);
end;
tamanho:= length(:dt_referencia);
for c in 1..tamanho loop
     nome := nome||substr(:dt_referencia,c,1)||' ';
end loop;
return(nome);
end;
end;
