title: Questions about getting data from multiple places in excel
body: <p>I have three pivots I'm pulling data from that look like this: </p>
  
  <pre><code>Work completed pivot
  DATE(start_time)    | userid    operation_id    Time estimated  Time Elapsed
  
  
  Fault pivot
  date(date_entered)  | userid    operation_id    Major   Minor
  
  Paid hours pivot
  for_day         | userid    Total
  </code></pre>
  
  <p>The time tracked for each operation is not present so I want to get an approximation by doing<br>
  hours_paid * (time_tracked_by_operation/time_tracked_for_all_operations) but I cannot figure out how to perform operations on multiple fields from a pivot.</p>
