Affiliates Pro – Empty Custom Fields [duplicated]

Hi,
Can you help me?
I’m trying to hide containing div if custom field is empty.

So for example a new registration would have the option to enter a facebook url to their personal facebook profile. On the home page I would have a div container for facebook with a facebook icon and next to the icon their facebook would display. I have this working but it the user does not use facebook and leaves the field empty then I would like to hide the containing div which wraps all this information removing the facebook url placement and icon all wrapped from the one div container.

Thank you,
Derek
