title: “Private Sub Worksheet_Change(ByVal Target As Range)” -need help re: range
body: <p><code>Private Sub Worksheet_Change(ByVal Target As Range)</code> </p>
  
  <p>I was hoping to ‘borrow’ this bit of code but was unsure what to place in for the range values. Why I wish to use it is for a data page for a workbook full of vlookups. </p>
  
  <p>On this page A through M is filled with data and occasionally is updated, by N through AB has formulas adding two of the data cells or merging information in them. RangeSource and Range Destination seem to be where I might need to adjust-HELP?</p>
  
  <p>Thank you in advance!</p>
