How to get custom fields for blogs shown on main site index page or anywhere.

I'm using the theme "NETWORK" and the index page of the main site will show the latest updated blogs including the latest post with it's thumbnail and blog title, I'm using static page with custom fields as the blogs' front page, I want this custom fields to be shown on the index page of the main site after blog title, and using this code below but it doesn't work, the custom field doesn't show.

<a href="<?php echo $options[0]->option_value; ?>">
<?php echo $options[1]->option_value; ?>
 <?php echo do_shortcode('[ct id="ct_subtitle_text_c7b9" property="title | description | value"]'); ?>
</a>
