title: Google Spreadsheet SCRIPT Check if edited cell is in a specific range
body: <p>I need to detect if changes made to a spreadsheet are being made within a certain range of data and if so, set the current update time. <br/><br/>
  The issue is, I have a spreadsheet that I edit headers and text on and I do not want the update time in a specific cell to be updated on the spreadsheet but when I edit the data in a range of cells, I DO want the update time changed.</p>
  
  <p>Here's what I have to update the time.</p>
  
  <pre><code>function onEdit(e) 
  {
    var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  
    ss.getRange("G10").setValue(new Date());
  } ​
  </code></pre>
  
  <p>I only want the date in G10 set if I edit certain cells (in a range "B4:J6")</p>
