BudgetService

[Moe]

Hi All,

I am trying to change the GetCampaigns.php example in the php library to 
Get Budget instead.

So I proceeded by changing the CampaignService to BudgetService. I am 
trying to retreive the name and amount of the budget. But I am getting the 
following error:

An error has occurred: [SelectorError.INVALID_FIELD_NAME @ selector; 
trigger:'na
me', SelectorError.INVALID_FIELD_NAME @ selector; trigger:'amount']


The following is a snippet of the code:

function GetBudgetExample(AdWordsUser $user) {
  // Get the service, which loads the required classes.
  $budgetService = $user->GetService('BudgetService', ADWORDS_VERSION);

  // Create selector.
  $selector = new Selector();
  $selector->fields = array('name', 'amount');
 // $selector->ordering[] = new OrderBy('name', 'ASCENDING');

  // Create paging controls.
  $selector->paging = new Paging(0, 
AdWordsConstants::RECOMMENDED_PAGE_SIZE);

  do {
    // Make the get request.
    $page = $budgetService->get($selector);

    // Display results.
    if (isset($page->entries)) {
      foreach ($page->entries as $budget) {
        printf("Budget with name '%s' and amount '%s' was found.\n",
            $budget->name, $budget->amount);
      }
    } else {
      print "No budgets were found.\n";
    }

    // Advance the paging index.
    $selector->paging->startIndex += 
AdWordsConstants::RECOMMENDED_PAGE_SIZE;
  } while ($page->totalNumEntries > $selector->paging->startIndex);
}

Thanks. Please I need a quick reply if possible.
