[160]  code error (Hack 55), top of the page;
The content of nusoap.php and also Google services has changed such that this code
always produces "no results", i.e. an error. The code at the top of the page must
read as follows:

$soapclient = new soapclient("http://api.google.com/search/beta2");

A local copy of the GoogleSearch.wsdl file does nothing, and the URL included in the
book also does nothing - I've tested both methods. In order to get the code to work
on a local copy of the .wsdl file, you'd have to alter the nusoap class, or at least
that's my initial understanding of the problem. I haven't yet read through the 4000-
plus lines of code in nusoap.php. I will test it again and make sure that error
reporting is active.
