How to turn code on/off over UserCP?

[Doc Great]

Doesn't work. Anybody out there

if ($vbulletin->userinfo['field6'] == 'On') 
{
<if condition="$GLOBALS['adsense_position'] == $post['postcount']">
$spacer_open 
<div style="padding:0px 0px $stylevar[cellpadding]px 0px"> 

<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center"> 
<tr> 
	<td class="thead" align="left">Sponsored Links</td> 
</tr> 
<tr> 
	<td class="alt1" align="center">

<!-- Werbung -->

	</td> 
</tr> 
</table> 

</div> 
$spacer_close 
</if>
}
