title: how to add leading zero to a text field in crystal reports
body: <p>I'm trying to think of a way to add a leading zero to a string field value. 
  For example I have 12345 but need a formula that would convert it to 012345. I'm new to Crystal as I know that this is probably a simple formula but cant seem to get it to work. </p>
  
  <pre><code>12345 =&gt; 012345  (add leading zero to make it 6 chars)
  </code></pre>
  
  <p>Thanks in advance. </p>
