BuddyPress.org

Hi, I would like to give it an anchor text instead content of the field? I tried couple ways but I got different errors… what I am making wrong? (I set the field as URL)

/* Function Buddypress */
function bbp_add_xprofile_field() { 
$user_donation = xprofile_get_field_data( 'Donation:', bbp_get_reply_author_id() ) ;

if (!empty($user_donation)) {
echo '<p>' . $user_donation . '</p>';
}
}
add_action('bbp_theme_after_reply_content', 'bbp_add_xprofile_field' );
