Limiting post content


#1

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: "
[php]

<?php content(30); ?>
"[/php] The functions.php file is quite large so I didn't post it here but can send it to anyone who would like to take a look at it. Can anyone tell why it's not finding the function 'content'? Thanks!
