Can someone PLEASE find an error with this regular expression code? I used it to validate an email
<p>Is there a problem with this regular expression? I've got jquery enabled and all that, so nothing is a problem, except this regex doesn't work, for some reason. Thanks!</p>

<pre><code>var thereg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
return thereg.test($("email").value);
</code></pre>
