SOAP:Lite error

[hemangm]

I am trying to make a SOAP:Lite call to WSDL that is available at

http://www.webservicemart.com/uszip.asmx?WSDL

program gets into $service->faultstring

when trying to do following declaration,

#!/usr/bin/perl
#SoapTest.pl
use strict;
use warnings;

use SOAP::Lite;

my $service = SOAP::Lite
-> uri('

http://webservicemart.com/ws/ValidateZip')

-> on_action( sub { join '/', '

http://webservicemart.com/ws/',

$_[1] } )
-> proxy('

http://www.webservicemart.com/uszip.asmx');

What am I missing???? TIA
