title: SAS Enterprise Guide: Report Showing Percentage Difference Between Columns
body: <p>I have designed the following report using the List Data task in SAS EG.</p>
  
  <ul>
  <li>1st Column: List of Products</li>
  <li>2nd Column: Sum of Q1 Sales</li>
  <li>3rd Column: Sum of Q2 Sales</li>
  <li>4th Column: Percentage Difference between Q1 and Q2</li>
  </ul>
  
  <p>The issue with my design is that when it comes to the totals row, it shows the sum of 4th column. I would like it to calculate the percentage difference between the total of Column 3 and 2.</p>
  
  <p>Thanks.</p>
