Hi all,<br><br>I would like to use the validator tag to validate data using either regexes or math expressions.  How can I do this?  I tried using the &quot;regex&quot; type, but I&#39;m not sure where to put the regex itself.  I tried putting it in a file that was in the filename attribute, but that didn&#39;t seem to work.  Essentially, I want to check if an integer input is even or not.<br>
