Adding a JS with wp_register_script, wp_enqueue_script; "jquery is not defined"

I have been messing with WordPress on localhost, but I’m having a problem adding a JavaScript to a page. In my functions.php, I have the following:

function addMyScripts()
                        get_template_directory_uri() . '/js/clever-dl.js',
                        array( 'jquery' ),
    wp_enqueue_script( 'clever-dl' );

add_action( 'wp_enqueue_scripts', 'addMyScripts' );

The page appears to render accurately, with all the paths correct and scripts being called in the right places. However, Firebug is telling me that “jquery is not defined” when it tries to run my script. (I’m using “jquery” instead of “$” to avoid conflicts.) Does anyone have any idea what I might be missing? Thanks in advance for your help!

/me slaps forehead. Should have checked the capitalization in the script itself; that’s jQuery with a capital Q. :-\
