Jquery issue in Muse??

Hey guys

I've been using Adobe Muse to create my website, and so far everything's been going really well.

I've just tried to add the Shoprocket codes so that visitors can still purchase things, but it doesn't seem to be working??

Shoprocket has said to insert the following code on any page that I want people to be able to checkout from, so that the cart appears etc.:

<!-- jQuery -->

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script><script>var $=jQuery.noConflict();</script>

<!-- Shoprocket JavaScript -->

<script language="javascript" src="https://space.shoprocket.co/frontend/sr.min.js?cid=10850"></script>

<!-- Shoprocket Basket Widget -->

<div id="sr-basket-widget" class="sr-right"><span class="sr-confirm-amount"></span></div>

and then I insert this code where I want people to be able to purchase a particular product from:

<a href="javascript:sraddtocheckout(91742);" class="sr-add">Add to Cart</a>

This is the particular page of my website that I have tried this on:

http://www.jenirohwer.com//ain-t-no-mountain-high.html

Clicking 'add to cart' does not seem to make anything happen, nor does clicking on the cart itself.

When I hover over 'add to cart' the following line appears in the bottom right hand corner of the screen (in Chrome):

javascript:sraddtocheckout(91742);

Someone please help me! I've been trying to get this working for nearly a week now and can't work it out

Thanks in advance!!!
