Conditional Help

[UKBusinessLive]

Hi guys

I need a little help and i hope that one of you guys can help me here

i'm using the conditional below, in my header

<if condition="$bbuserinfo['usergroupid'] == x">
<meta HTTP-EQUIV="REFRESH" content="0; url=http://www.ukbusinesslive.co.uk/warning.html">
</if>

But the problem is that, it keeps repeating, the HTML code i wrote has a redirect back to the forum URL, But by using the above it keeps repeating in a loop

Is there a way to make a conditional run once and then end??

Thanks in advance

Gerry
