[AJAX] Script zurb impossible à mettre en place

Bonjour tout le monde

J'essaye de mettre en place le script suivant : http://www.zurb.com/playground/ajax_upload (New Hotness)

Mais impossible, il n'y a rien à faire, cela fait plusieurs jours que je suis dessus mais que dalle.

Je ne peux malheureusement pas donner les pages de tests (projet confidentiel) mais voici en gros les derniers essais (j'ai carrément fait tout pointer vers leur site et tout viré ...) :

				<p><strong>Now try this variation.</strong> We ditch the upload button in favor of a save button and fire the AJAX upload event as soon as a file 
					is selected. The image is processed server side and a thumbnail is loaded onto the existing page. Dosen't that feel so much better?</p>
 
				<p>We now have a visual representation (imagine that) of the image we selected. This is particularly useful in larger forms when 
					many fields will be submitted with a single action. It allows the user to review the form before pressing save and see what image
					 (or images) they selected.</p>

Impossible de trouver ces deux fichiers :

Citation:

// This function will be located in: /public/javascripts/layouts/playground.js
if (typeof initLayout == 'function') initLayout();

// This function will be located in: /public/javascripts/controllers/playground.js

Si quelqu'un peux le tester et trouver comment le faire fonctionner, je le remercie d'avance.

J'oubliais, j'ai mis les bons droits sur le serveur.

Merci d'avance.
