title: How to get the Row index of the active cell in a specific range
body: <p>I want to get the row index of the active cell<br>
  relative to a supplied range... </p>
  
  <p>to clarify I want the index of the row inside of the range</p>
  
  <p>Something like </p>
  
  <blockquote>
    <p>RangeRowIndexOfActiveCell( range1 )<br></p>
  </blockquote>
  
  <p>should return the row index of active cell relative to the specified range<br></p>
  
  <p>(-1 if ActiveCell is not inside range... 
  but that is superfluous)</p>
  
  <p>?any ideas</p>
