I have this stored procedure:
procedure mulnum (
numuno in number,
numdos in number,
resultado out number) as
begin
resultado := numuno * numdos;
end;

I already tested it with D2K and it works (But I dont like D2K).

Here is my code in Delphi:
procedure TForm1.Button1Click(Sender: TObject);
begin
with OraclePackage1 do
begin
OraclePackage1.CallProcedure('MULNUM',[15,5,parInteger]);
Label1.Caption:='15 Times 5 is'+IntToStr(GetParameter(2));
end;
end;

I receive the error "ORA-06550 line 2 column 10" and then the "PLS-00225 Subprogram or cursos MULNUM reference is out of scope" and then the "ORA-06550: line 2 , column 3 :PL/SQL Statment ignored"

So stupid question?? yes/no? either way and dont know whats going on.
