Show profile description in bubble map

Hi,

I managed to add email reading this post : https://wpgeodirectory.com/support/topic/show-email-address-in-map-bubble/

I would like to add the profile description using the following code, but I don’t manage to create the $post variable in post_functions.php

Thanks,
Marc.

$show_listing_excerpt = apply_filters('geodir_show_listing_post_excerpt', true, 'listview', $post);
if ($show_listing_excerpt) {
    if ( isset( $character_count ) && ( $character_count || $character_count == '0' ) ) {
        $content_out = geodir_max_excerpt( $character_count );
    } else {
        $content_out = get_the_excerpt();
    }
    if ( ! empty( $content_out ) ) {
        echo '<span class="geodir_profile">' . $content_out . '</span>';
    }
}
