Excerpt pulling wrong data.

If I enter an excerpt at all it formats it but with the start of the post and not what I had entered explicitly for the excerpt. If I don’t enter an excerpt it displays one anyways and uses the entire post as the excerpt. I’ve tried countless things and read countless blog posts. I’m not really sure what I could of messed up. The site is at http://machbytes.com/

My goal is for it to display w/e I enter for the manual excerpt for each post.

My functions.php for the theme has

// =========================
// = Change excerpt lenght =
// =========================
add_filter('excerpt_length', 'my_excerpt_length');
function my_excerpt_length($length) {
return get_option('imbalance_excln'); }

// =================================
// = Change default excerpt symbol =
// =================================
function imbalance_excerpt($text) { return str_replace('[...]', '...', $text); } add_filter('the_excerpt', 'imbalance_excerpt');

and the index.php has

<?php
   if (function_exists('has_excerpt') && has_excerpt()) the_excerpt();
   else the_content('Read on...');
//<?php the_excerpt();
?>
