If you want to echo BuddyPress’s extended profile fields outside the loop, you need to add the $bp->loggedin_user->id parameter.
Here’s the code using a Genesis hook (substitute a hook for your theme):
function show_extra_profile_fields() {
global $bp;
$myfield = xprofile_get_field_data( 'Field Name', $bp->loggedin_user->id );
echo $myfield;
}
add_action( 'genesis_before_loop', 'show_extra_profile_fields' );
Add html tags to the echo statement and you’re in business.
Blessings.
