Here is my code that works for 4.2.2.. Difference is that I have Postbit Tabs. But will work..
Code:
<!-- Twitter -->
<vb:if condition="$post['field#']">
<a href="https://twitter.com/{vb:raw post.field#}" TARGET="_blank"><img src="/images/site_icons/socialpopup/twitter.png" alt="Twitter"> </a>
</vb:if>
<!-- Facebook -->
<vb:if condition="$post['field#']">
<a href="https://www.facebook.com/{vb:raw post.field#}" TARGET="_blank"> <img src="/images/site_icons/socialpopup/facebook.png" alt="Facebook"> </a>
</vb:if>
<!-- Google Plus -->
<vb:if condition="$post['field#']">
<a href="https://plus.google.com/{vb:raw post.field#}" TARGET="_blank"> <img src="/images/site_icons/socialpopup/googleplus.png" alt="Google+" /> </a>
</vb:if>
<!-- YouTube -->
<vb:if condition="$post['field#']">
<a href="http://www.youtube.com/user/{vb:raw post.field#}" TARGET="_blank"> <img src="/images/site_icons/socialpopup/youtube.png" alt="Youtube" /></a>
</vb:if>
The above code will line up the icons side by side. On in the on icon on each line like the above code. Of course replace # with your field number
