title: Summarizing Shared Variable in Crystal Reports
body: <p>I have a formula that uses two shared numbers in it. I now need to sum this formula. If I use running total or sum functions, the formula does not show in the pick list. </p>

  <pre><code>({@Shared Total Wt Lbs}*{@Shared Scrap})/100
  </code></pre>
