Excerpt issue with post type

Hi There

I was hoping someone could help me out with a get post id and excerpt issue I am having for this page template page.

In the list you will see that I have one speaker listed below the main body content and the excerpt text being displayed is pulling the content from the page title & content, when if should be pulling the text from the post type.

This is the code I am using to pull the article information.

<article>
<div class=”row”>
<div class=”six mobile-two columns”>
<?php echo ‘ID).'”><h4 class=”speaker-name”>’.get_the_title($post_object->ID).'</h4>‘ ?>
<span class=”speaker-title”><?php the_field(‘speaker_title’, $post_object->ID); ?></span>
<div class=”excerpt hide-for-small”><?php
global $detect;
if ($detect->isTablet()) {
echo ‘<p>’.limit_excerpt(‘150′).'</p>’;
} else {
echo ‘<p>’.limit_excerpt(‘250′).'</p>’;
}
?>
</div>

Can anyone make some suggestions to help with this fix.

Thank you very much
