The archive page goal provided in github snippet doesnt work?

https://github.com/impress-org/give-snippet-library/blob/master/customized-templates/archive-give_forms.php

Hi, the snippet provided here… outputting the goal no longer works? tested on my theme and default WP theme. It seems that when i remove the conditional

if ( $goal_option == 'yes' ) {

then it works fine, however, this also shows the error message on forms that dont have a goal.

the code to output the goal is

// Output the goal
$goal_option = get_post_meta( $id, '_give_goal_option', true );
if ( $goal_option == 'yes' ) {
$shortcode = '[give_goal id="' . $id . '"]';
echo do_shortcode( $shortcode );
}

Hope that helps.
