Warning call_user_func_array() - how to fix? (1 post)

    I have this error:

    Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'mc_script' was given in /home5/optimal9/public_html/wp-includes/plugin.php

    It's probably being caused by my new script in functions.php.

    It's based on an Art Of Blog post about customizing a Mailchimp Signup Form (http://www.artofblog.com/styling-a-mailchimp-form/)

    I don't know what is causing this error -- the script works just fine. But I need to fix whatever's causing the warning because users can see it.

    Here is the functions.php function I added:

    //add mailchimp scripts before body close
    function mailchimp_scripts() { ?>
    <script type="text/javascript">
    var mc_custom_error_style = '';
    </script>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
