NuSOAP error: Invalid value...

[eluser]Varzock[/eluser]
Hi guys,

I've started studying and using NuSOAP for CI few days ago and now I have ran into a problem. Maybe it's a just a minor one, something little that I haven't noticed but when I try to test the NuSOAP library it gives me this error "Invalid value...". I got the NuSOAP library from here: http://codeigniter.com/wiki/CI_Nusoap_Library/

here's my code:

Code:

$this->load->library('nusoap');
$soapclient = $this->nusoap->getProxy(
    'http://soap.search.msn.com/webservices.asmx?wsdl');
    
$test = array('Request' => array(
            'AppID' => 'MSN_SEARCH_API_KEY',
            'Query' => 'Seinfeld',
            'CultureInfo' => 'en-US',
            'SafeSearch' => 'Strict',
            'Flags' => '',
            'Location' => '',
            'Requests' => array(
                    'SourceRequest' => array(
                            'Source' => 'Web',
                            'Offset' => 0,
                            'Count' => 50,
                            'ResultFields' => 'All'))));                    

$result = $soapclient->call(
    'Search',
    $test
);

I enabled logging and debugging and it seems it actually is sending the right kind of info to the SOAP server but it still gives me this error.

Please please point my mistake and prove my stupidity because I'm getting irritated
