title: Google Datastudio: sum of several fields with the same name, how to target specific field
body: <p>I have blended data with three fields, all named "Pageviews". When I create a new field which should be the sum of these three, I enter "Pageviews+Pageviews+Pageviews" which calculates the first field three times.</p>
  
  <p>I know that internally, Google Studio stores these fields using a table alias such as table0.Pageviews.</p>
  
  <p>If I knew what the table alias was, I could then write something like:</p>
  
  <pre><code>table0.Pageviews+table1.Pageviews
  </code></pre>
  
  <p>I cannot drag and drop the fields into the formula section, and doing a html code inspection does not yield a clue to what the table alias is.</p>
  
  <p>How can I make sure I have the sum of three fields which all have the same name?</p>
