Using google cart gadget locally

Question

You might be aware that google checkout is closing in Novemeber, and rather than spending hours writing a new cart I'm hoping it's possible to move the google cart gadget to local...

I have it running on jsfiddle

http://jsfiddle.net/4SVRx/5/

But as soon as I make that javascript local I get nothing

http://jsfiddle.net/4SVRx/6/

Is it not possible to use the code locally?

links to jsfiddle must be accompanied by code. There's a sizeable amount of code in jsfiddle I don't want to post it here

<div class="basket">

etc.......
