hrmm ok, an example of my search

result

looks like this:

{
  "recordType": "itemfulfillment",
  "id": "8161",
  "values": {
    "internalid": [
      {
        "value": "8161",
        "text": "8161"
      }
    ],
    "shipmentPackage.trackingnumber": "9405515901965736183160"
  }
}

the following didn't work...

var itemFulfillmentId = result.getValue({
                name: 'shipmentPackage.trackingnumber'
            });

nor did

result.getText

,

result.getSublistValue

, or trying to access the value directly

result['values']['shipmentPackage.trackingnumber']

- what am I missing here lol
