title: Remove letter from a string access VBA
body: <p>I have a string sStr that contains letters and numbers.I'm trying to remove letters from a string.</p>
  
  <p>For eg: sStr= "P441"  or sometimes sStr="BK471" . </p>
  
  <p>I tried using 
  <code>Right(sStr,3)</code> and <code>split</code></p>
  
  <p>which gives me 441. since the string sStr may contain 2 letters ("BK471") sometimes,  how do i remove letters in vba .  </p>
