title: Reg Ex - not allowing zero
body: <p>Excuse my ignorance. My knowledge of regular expressions is extremely limited.</p>
  
  <p>I have the following regular expression on a regular expression validator. </p>
  
  <pre><code>^(\d{1,3},?(\d{3},?){0,2}\d{3}|\d{1,3})$
  </code></pre>
  
  <p>It currently allows zero. I need to update it so that it does not allow a value of 0.</p>
  
  <p>[Edit: Just to clarify, I would like it to exclude a value of zero rather than a singular "0" - thanks]</p>
  
  <p>Any help would be greatly appreciated.</p>
  
  <p>Thanks
  zaps</p>
