title: Using VBA turn on a cell's double-underline
body: <p>I've written (my first VBA) code to sum a column of numbers and draw a single, thin border around it.</p>
  <p>I'd like to put a double-underline below the total cell.</p>
  <p>Here's how I thought it would work.</p>
  <pre><code>rng.Parent.Cells(iRow, iCol).Borders(xlEdgeBottom).LineStyle = XlLineStyle.xlDouble
  </code></pre>
