MSM760 Soap Call returning an unexpected response

[Master_lain]

Good evening,

      I'm trying to work out a simple proof of concept monitoring/data collection system using soap. I'm starting off with some basic HP provided PHP samples.  

I'm trying to poll an MSM760 to report the status of its controlled APs, everytime I call ControlledNetworkGetDiscoveredAPStatus it returns a bad response and fails

$rc = $c->ControlledNetworkGetDiscoveredAPStatus("Group", "Default Group", "All_States");

Results in

string: <Validation constraint violation: tag name or namespace mismatch in element <param1>>
code:   <SOAP-ENV:Client> 

I'm using the HP supplied WDSL and soapapi-inc.php of like versions

Attached is my code,
Thanks for any insight into this, I've called everything according to examples and its getting frustrating :O

As a side note... I can call other controlled mode related items just fine eg.

$rc = $c->ControlledNetworkGetGroupList();

 results in the list of groups on the controller.

Thanks,

Ryan

EDIT: Wouldn't attach my file so I've embeded it...
