Calling .Net web service using a PERL client.

I need to call a .Net web service that takes an array or object as a
parameter from a PERL client. I have been trying to use the PERL SOAP::Lite
package to do this without success. I can call one that takes a simple
type, such as int or string, but not an array or object. Please help!!! My
code that I have written to call the web service and the SOAP packets that
get sent and received are below. It seems like no matter what I do I cannot
get it to recognize the array that I pass. Please CC my email address with
any responses. My address is as follows with the $# removed:
J$#im.Fo$#wl$#er@E$#D$#S$#.c$#o$#m
Thanks in advance for any assistance.

use SOAP::Lite;

my @web;
@web[0] = '234234';
@web[1] = 'Test1';
@web[2] = '3454545';
@web[3] = 'Test2';

my $s = SOAP::Lite
            -> uri('EDS.Galileo/')
            -> proxy('http://testedsapps.weyer.com/Galileo/Galileo.asmx')
            -> on_action(sub{sprintf '%s%s', @_ })
            -> on_debug(sub{print@_}) ;
            ;
$result =
$s->UpdateIncident(SOAP::Data->name('TicketValues')->value(SOAP::Data->value
(\@web)));

unless ($result->fault) {
    if (length ($result->result()) == 0)
    {
    print "result = ".$result->result()."\n";
    }

} else {

print "error ".$result->faultstring."\n";

unless ($result->fault) {
    if (length ($result->result()) == 0)
    {
    print "result = ".$result->result()."\n";
    }

} else {

print "error ".$result->faultstring."\n";
}
