在广告词脚本中添加活动选择器

我有一个定位脚本的出价，该脚本针对的是带有标签的关键词。标签包含所需的位置，脚本会调整关键字的出价以达到该位置。现在，脚本针对任何带有标签的关键字。我正在尝试编辑脚本，以便在我选择的活动中查找标记的关键字。我尝试将.withCondition（CampaignName='My Campaign Name'"）添加到labelIterator变量中，但没有成功。有人能为我指明正确的方向吗？

* Average Position Bidding Tool
*
* This script changes keyword bids so that they target specified positions,
* based on recent performance.
*
* Version: 1.2
* Updated 2015-09-28 to correct for report column name changes
* Updated 2016-02-05 to correct label reading, add extra checks and
* be able to adjust maximum bid increases and decreases separately
* Google AdWords Script maintained on brainlabsdigital.com
