Limiting post content

[sepia53]

Hi. Trying to use the "Excerpt or Content Word Limit in WordPress: Redux" code to limit my Amazon product description content but to no avail. Getting the "Fatal error: Call to undefined function content() in index.php on line 36". The following is the code in the index.php file that makes the call: "

<div class="post-content">

  <?php content(30); ?>

<!-- <?php the_post_excerpt($excerpt_length=30); ?> -->

</div><!-- POST CONTENT --> "

The functions.php file is quite large but I attached it so anyone who would like to take a look at it.

Can anyone tell why it's not finding the function 'content'? Thanks!
