title: Get second letter in expression in SSRS
body: <p>I have a list of machines listed like so:</p>
  
  <pre><code>M101
  M102
  M201
  M202
  M203
  </code></pre>
  
  <p>What I desire to return is </p>
  
  <pre><code>1
  1
  2
  2
  2
  </code></pre>
  
  <p>My question is how would I extract my desired return of the second charcter from my group expression? My field is <code>=Fields!machine.Value</code></p>
