title: Excel conditional formatting based on cell and adjacent cell values
body: <p>Is it possible to format a cell in Excel based on the cell above it's value.
  Basically I'm compiling a spreadsheet and I want the cell to be highlighted in light green if the value has gone down since the entry above and I want it to go red if it has increased.</p>
  
  <p>I'm sure its fairly simple but I just cant get it to work.</p>
  
  <p>Any help would be greatly appreciated.</p>
