Need help with a minor condition or maybe rewriting this

[demo7up]

<vb:if condition="$post['userid']">
<vb:if condition="$post['field44']">

    <div class="jdm_plate" style="background-image:url(http://nycjdm.com/images/styles/blackstealth/misc/license_plates/{vb:raw post.field44}.png);">
<p><b>{vb:raw post.field45}</b></p>
