calculate the freight to send for our customer

[loucospormusica]

Here in Brazil people use cep to calculate the freight to send for our customer. My doubt is that I obtained a data base to calculate, has a store that it uses this system, as I can integrates it in my store?

script language="JavaScript">
function formataCEP (keypress, objeto)
{
campo = eval (objeto);
caracteres = '0123456789';
if (String.fromCharCode (keypress) == '.')
	event.returnValue = false;

if ((caracteres.search(String.fromCharCode (keypress))!=-1) && campo.value.length <= 9)
{
	if (campo.value.length == 5) 
   		campo.value = campo.value + '-';
}
else if (keypress != 13)
	event.returnValue = false;
}

function formataCEP_Special_Key (keypress, objeto)
{
if (keypress == 8) {// backspace
	if (campo.value.length == 7) 
		  campo.value= campo.value.substr(0,6);
}
else if (keypress == 46) {// DEL
	campo.value=campo.value.substr(0, campo.value.length-1);
	if (campo.value.length == 6) 
		  campo.value= campo.value.substr(0,5);
}
}

function validate_cep()
{
if (document.calcula_frete.elements["cart_CEP"].value.length != 9) {
	alert("CEP Inv?lido");
	document.calcula_frete.elements["cart_CEP"].focus();
	return false;
}
else 
	return true;
}

function AutoPAC() {document.calcula_frete.submit(); };
function AutoBRASPRESS() {document.calcula_frete.submit(); };
function AutoENCOMENDA_NORMAL() {document.calcula_frete.submit(); };
function AutoGRATIS() {document.calcula_frete.submit(); };
function AutoSEDEX() {document.calcula_frete.submit(); };
