Can someone help with wp_enqueue_script?

I’ve read most of the posts on this forum about wp_enqueue_script, but I’m just not getting it.

I’m just trying to write a pretty simple plugin. Here is what I have going.
I’m using a class to write the plugin. This works, I can install the plugin and some db tables that go along with it.

On one of the admin pages I want to use a jquery script so I’m thinking that I need to do this: wp_enqueue_script('ht-dynanmic-form', plugins_url('wp-hobby-tracker/js/jquery-dynamic-form.js'), array( 'jquery', 'jquery-ui'),'1.0', true);

From what I have read, this should initiate jquery and jquery-ui, and then put the script tag in the footer of my page. I can’t find any reference when I search through the page source however.

Here is a quick and dirty overview of my plugin thus far. Obviously not the working code, but it should give you an idea.

if !class then create the class{
   functions to generate pages and do stuff{}
    }
function to add dbstuff{}
function admin menus{
   add_menu_page
   add_submenu_page
   wp_enqueue_script is here}

register_activation_hook(__FILE__,'dbstuff');
add_action('admin_menu','admin menus');

Thanks for any help or advice.
