Javascript Error when attempting nlapiCreateRecord

I have the following javascript.

 function create_case() {      var company={"company": { "name": "CU000001 Anonymous Customer", "internalid": "3" }};      var contact={"contact": { "name": "fake", "internalid": "781" }};      var due_date="7/20/2012";         var record=nlapiCreateRecord('supportcase');      record.setFieldValue('title', 'test');      record.setFieldValue('incomingmessage', 'test incoming message');      record.setFieldValue("company", company);      record.setFieldValue('contact', contact);      record.setFieldValue('custeventduedate', due_date);            id = nlapiSubmitRecord(record, true);      return record;  } 

And I'm getting this error.  With a similar one for contact.

 {      "error" : {          "code" : "INVALID_KEY_OR_REF",           "message" : "Invalid company reference key {company={name=CU000001 Anonymous Customer, internalid=3      }  } 

When loading an existing supportcase with the following javascript

 function create_case() {      var record=nlapiLoadRecord('supportcase', '46145');      return record;  }
