Javascript in wordpress page, using child theme

Hi all.
I’m trying to use some javascript that will display the day, on just one of my pages. Through wordpress I have included this directly on the page:

<script type="text/javascript" src="/scripts/happydate.js"></script>
<script type="text/javascript">
<!--
happydate();
//--></script>

I created a file named happydate.js with the code below and put in a scripts folder under my childtheme directory (wp-content/themes/childtheme/scripts):

<script type="text/javascript">

      <!--
      // Array of day names
      var dayNames = new Array("Sunday","Monday","Tuesday","Wednesday",
              "Thursday","Friday","Saturday");
      var now = new Date();
      document.write("Happy " + dayNames[now.getDay()] + ".");
      // -->

    </script>

I also tried adding both the codes below (separately, at different times) to my functions.php file (in the same childtheme directory). Neither of them worked for me. 

<?php
function add_my_scripts(){
wp_register_script(‘happydate’,
get_bloginfo(‘stylesheet_directory’).’/js/happydate.js’, array(‘jquery’),’1.0′);
wp_enqueue_script(‘happydate’);
}
add_action(‘init’, ‘add_my_scripts’);
?>

< ?php
if ( !is_admin() ) { // instruction to only load if it is not the admin area
?? // register your script location, dependencies and version
?? wp_register_script('happydate',
?????? get_bloginfo('stylesheet_directory') . '/scripts/happydate.js',
?????? array('jquery'),
?????? '1.0' );

?? // enqueue the script
?? wp_enqueue_script('happydate');
}
?>

I have no idea where in the steps above I went wrong, or if all the syntax is correct. Any insight is appreciated. I have a little bit of a grasp on this stuff, but I’m definitely a newbie. Be gentle!

Thanks in advance.
