title: Calculating with pivot table in Excel
body: <p>Really stupid question but can't seem to find an answer. I have a a worksheet with columns name, report, success. Name and report are text, success is 1 or 0.</p>
  
  <p>I made a pivot table to summarize the results. Again three columns: Name, Number of reports (count of reports), Number of success (sum of success).</p>
  
  <p>Now I want to have a success percentage. So sum of success divided by count of reports. How to do that, dynamically?</p>
