title: Search for a value in another sheet and copy row if match?
body: <p>This is my sample spreadsheet:</p>
  
  <p><a href="https://docs.google.com/spreadsheets/d/1ropciT6djExmDh73GO__rNNg1Ny3FlN-Qwzkm1Yan7A/edit?usp=sharing" rel="nofollow">https://docs.google.com/spreadsheets/d/1ropciT6djExmDh73GO__rNNg1Ny3FlN-Qwzkm1Yan7A/edit?usp=sharing</a></p>
  
  <p>It has three sheets:</p>
  
  <ol>
  <li>Accounts: list of account for Facebook (it's just a random example)</li>
  <li>Reviews: list of accounts that has already posted a review on Facebook</li>
  <li>Pivot table</li>
  </ol>
  
  <p>How can I get a list of accounts IDs that has not posted a reviews on Facebook? I can't figure it out. I know I can get a list of accounts that have posted, as you can see on the spreadsheet, but not the other way around. </p>
