Updating A Customer Record In PHP

Hi,

I'm trying to update the phone number for a customer record. My problem is that I'm getting a reponse saying:


Please enter values for Category, Lead Source.

This is a little confusing since the schema says they are not required and its an update so I shouldn't be having issues with this part.

I would also be fine adding this info if I had any idea how to access it. The initial response that I'm getting form the get() is not showing me any leads to what optional values for these might be.

$customer = new nsRecordRef();
$fields['type'] = 'customer';
