Hello,<br><br>   Long week :) -- I have completely forgotten about the regex module.  Thank you all.<br><br><div class="gmail_quote">On Thu, Sep 10, 2009 at 9:57 AM, Brandon Armstead <span dir="ltr">&lt;<a href="mailto:brandon@cryy.com">brandon@cryy.com</a>&gt;</span> wrote:<br>

<br>Does anyone have a solution so I can keep the same matching, except exclude matching &quot;unknown|Unknown&quot; when reason=unknown, however match it in all other conditions?<br><br>Thank you for any and all help ahead of time.<br>
