title: Drag down formula and change COLUMN references instead of ROWS
body: <p>I have this formula in Excel, in row E5:</p>
  
  <pre><code>=SUM(Banco!H$5;Banco!H$6;Banco!H$8;Banco!H$9;Banco!H$10;Banco!H$11)
  </code></pre>
  
  <p>I need it to change the COLUMN references instead of ROWS when I drag it down (basically behave like I was dragging it across)... For example:</p>
  
  <pre><code>=SUM(Banco!I$5;Banco!I$6;Banco!I$8;Banco!I$9;Banco!I$10;Banco!I$11)
  =SUM(Banco!J$5;Banco!J$6;Banco!J$8;Banco!J$9;Banco!J$10;Banco!J$11)
  =SUM(Banco!K$5;Banco!K$6;Banco!K$8;Banco!K$9;Banco!K$10;Banco!K$11)
  </code></pre>
  
  <p>Any clues?</p>
  
  <p>Thanks a lot!</p>
