Apart from the style info (the hack for this is available here) then the rest just follow this simple layout
Code:
<if condition="$post[fieldx]">Text: $post[fieldx]</if>
Replacing the x with the profile field number obtainable via the ACP and the word text with whatever you want it to display as.
Put that whereever you want it to show in your postbit or postbit_legacy template.
