[vB4] How does one go about toggling individual notifications via Profile field?

[vauge]

Why does the following not work?

Template: navbar_notifications_menubit

<vb:if condition="($notification.phrase != 'XYZ') && ($bbuserinfo['field20'] != 'No')">
<li><a href="{vb:raw notification.link}"><span>{vb:raw notification.total}</span> {vb:raw notification.phrase}</a></li>
</vb:if>

If the XYZ is found, it doesn't show any notifications. I want to show all notifications but XYZ.

Thanks for your time.

Edit: I figured it out, I hacked the code so it does not add the notification if the profile field is set.
