Creating a multi-step signup form (jquery help)

Here is my site

I’m brand new at using jquery so I’m not sure where to start.

Here is the tutorial I am following.

I am stuck at this step:

We need load jQuery library inside the page and then to use two plugins:

– jQuery UI, the most famous plugin used to extend the jQuery functionality.

– jQuery inputfocus, my jQuery plugin used to manage focus and blur events of the form.

Anyway the example is ready to use and it needs only to change the form action with the link of your php file used to store data and to edit the jQuery line 125 to: $(‘form’).submit();. You can also decide to use an AJAX calls to send the informations to server, and again it’s very easy to implement.

Basically, I have looked through the WordPress articles, but could someone put it in plain english for me? What files do I need to load where? Where do I add the enque_script? Thanks!
