line 10 is the soap thing, right? I don't know about SOAP. But, I know a little bit about debugging.

And turn on SOAP::Lite debug mode.. there might be one.. use SOAP::Lite +trace; ?

Looks like you have chained method/class calls. Maybe you can break it up... instead of

print SOAP::Lite
  -> proxy('http://homepages.feis.herts.ac.uk/~123456/cgi-bin/policy.c
+gi')
  -> uri('urn:policy')
  -> checkPolicyPrice($policyCode,$date)
  -> result;

Something like

use Carp;
my $s = new SOAP::Lite +trace; # not sure if this goes on the use stat
+ement or the optional constructor method
$s->proxy('http://homepages.feis.herts.ac.uk/~123456/cgi-bin/policy.c
+gi') or confess;
$s-> uri('urn:policy') or confess;
$s-> checkPolicyPrice($policyCode,$date) or confess;
my $output = $s-> result or confess;
print $output;

That may help track down the problem.
