title: Clear contents in Cells based on String/empty cell
body: <p>I am trying to clear cell contents if I find "na" as a cell value or if the cell is already blank.</p>
  
  <p>Example looks like this:</p>
  
  <pre><code>Rep Intakes Var Plan CAL Rep Intakes    Act CAL Rep Intakes
  na                  373.00                      na
  8.00                371.00                     374.00
  23.00               379.00                     358.00
  69.00               398.00                  
  -18.00              175.00                     148.00
  11.00                 na                       252.00
  </code></pre>
  
  <p>My numeric column start from E to ARA
  I want to write VB code which looks at given column range and checks each cell to check whether it is empty or "na". In both cases it should clear the cell. </p>
