Business Catalyst Problem Using API to insert/update

Question

Hi,
I am trying to use the API to insert/update products. But have been getting the following error in the response.

Content-Length: 370

I have looked through my request and cant see anything wrong so was wondering if anyone else can, or if there is something I have missed (or not setup properly), i'm sure its probably an obviously mistake that i just cant find. below is my request

I am successfully doing API Product Updates, not tried Creates yet.
From the WSDL you need theses fields;
'supplierCommission' => 0,      // type="s:double"/>
'weight'             => 2,      // type="s:int"/>
'inventoryControl'   => false,  //  type="s:boolean"/>
'canPreOrder'        => false,  //  type="s:boolean"/>  'captureDetails'     => false,  //  type="s:boolean"/>              
'isOnSale'           => true,   //  type="s:boolean"/>              
'hideIfNoStock'      => false,  //  type="s:boolean"/>              
'isGiftVoucher'      => false,  //  type="s:boolean"/>              
'enableDropShipping' => false,  //  type="s:boolean"/>              
excludeFromSearch'  => false,  //  type="s:boolean"/>              
'cycletypeCount'     => -1,     //  type="s:int"/>
+ the other arrays or the update wipes out data.
Experimentation seems to be the key
