The prediction form (both shortcode and prediction page) miss this functionality. I will fix it in the next version (2.4.0). If you can’t wait, change lines 804-808 in class-football-pool-pool.php to:
$points = $question['points'] == 0 ? __( 'variable', FOOTBALLPOOL_TEXT_DOMAIN ) : $question['points'];
$output .= sprintf( '<span class="bonus points">%s %s'
, $points
, __( 'points', FOOTBALLPOOL_TEXT_DOMAIN )
);
if ( ! $this->question_is_editable( $question['question_timestamp'] ) ) {
$output .= sprintf( '<a title="%s" href="%s">',
__( 'view other users answers', FOOTBALLPOOL_TEXT_DOMAIN )
, esc_url(
add_query_arg(
array( 'view' => 'bonusquestion', 'question' => $question['id'] ),
Football_Pool::get_page_link( 'statistics' )
)
)
);
$output .= sprintf( '<img alt="%s" src="%sassets/images/site/charts.png" />',
__( 'view other users answers', FOOTBALLPOOL_TEXT_DOMAIN ), FOOTBALLPOOL_PLUGIN_URL );
$output .= '</a>';
}
$output .= '</span></p>';
