Usually you can get a sense of how to do a condition by looking at others in the same template. In your case, see this one:

<if condition="$post['field2']"><div>$vbphrase[location_perm]: $post[field2]</div></if>

You should be able to copy that and change field2 to fieldx for your field and then just change the phrase being used also. So....

<if condition="$post['fieldx']"><div>Whatever: $post[fieldx]</div></if>
