Show item on profile page if "x" field is populated

Something like this:

Code:

<if $userfields['fid8'] then>Button Code</if>

If you include the {$userfields['fid8']} in the button code, maybe it is better if you sanitize it.

The other method is, only display the button if the value of the $userfields['fid8'] is matched with a specific format.
