Showing Advertisement on All Pages except showthread

[David Karol]

I put an advertisement in my showthread template, so I don't want vBulletin's 'built-in' footer advertisement to show there too. I have the following code for the built-in advertisement (Above Footer placement), however the code inside the if statement is still showing on showthread pages.

<if condition="THIS_SCRIPT != 'showthread'">

<vb:literal>
<div align='center'>
<!-- AllPages_Leaderboard_Footer_728x90 -->
***GOOGLE CODE HERE***
</div>
</vb:literal>

</if>

Does anyone know what I'm doing wrong? Internally, could there be a vb:literal around everything in that text box?

Here's a link to one of our showthread pages. Note that there may be empty space in the bottom footer ad, due to how Google is serving them.

Thanks,
David
