Problem with function parameters

Hi :

 

I have installed Pg 8.08

 

I create this function :

CREATE OR REPLACE FUNCTION CALCULO_VALOR_LIQUIDO_HELPDESK( nTipoDesconto SMALLINT,
                                                           nTipoComissao SMALLINT,
                                                           nDesconto NUMERIC,
                                                           nComissao NUMERIC,
                                                           nTotal NUMERIC )
RETURNS NUMERIC AS $$

 

DECLARE
nValorDesconto NUMERIC(14,2);
nValorComissao NUMERIC(12,2);

 

BEGIN
    nValorDesconto := 0;
    nValorComissao := 0;

 

    IF nTipoDesconto = 0 THEN
        nValorDesconto := nDesconto;
    ELSE
        nValorDesconto := ( nTotal * nDesconto ) / 100;
    END IF;

 

    IF nTipoComissao = 0 THEN
        nValorComissao := nComissao;
    ELSE
        nValorComissao := ( nTotal * nComissao ) / 100;
    END IF;

 

    RETURN nTotal - nValorDesconto - nValorComissao;
END;
$$ LANGUAGE plpgsql
CALLED ON NULL INPUT
SECURITY INVOKER;

 

When i test this function, i call the function with this parameters :

 

SELECT CALCULO_VALOR_LIQUIDO_HELPDESK( 0, 1, 10, 10, 1000 );

 

This is the error that happens:

 

ERROR: function calculo_valor_liquido_helpdesk(integer, integer, integer, integer, integer) does not exist
SQL state: 42883
Hint: No function matches the given name and argument types. You may need to add explicit type casts.

 

I dont now what the two first parameters are see as integer. When 0 and 1 are true smallint values.

 

What is happeining here?

 

Thanks in advance.
