Wait a second. It's not the Mood Manager. Duh, use this:

<if condition="!$post['field19'] && !$post['field2'] && !$post['age']">
<div class="rm_userinfo" align="center">
	<if condition="$post['field19']"><strong>Real Name:</strong> $post[field19]<br /></if>
	<if condition="$post['field2']"><strong>$vbphrase[location_perm]:</strong> $post[field2]<br /></if>
	<if condition="$post['age']"><strong>$vbphrase[age]:</strong> $post[age]</if>
</div>
</if>

The catch, though, is all 3 fields need to be populated in order for it to display. If either field is left blank, then none will be displayed. You can modify the <if> container to check against whichever field you wish rather than all 3, it's up to you.
