Question about Mini Shopping Cart

[Larrrry]

I am trying to insert the javascript for a mini shopping cart into my customized page, but it seems not to recognize the cookie. It prints out the Shopping cart title and the shopping cart graphic but when it gets to the "if (start == -1) //No cart cookie" line in the javascript it tells me there is no cookie (or can't find it). I go to the checkout page and the items are there but not on my page. The serial number is correct.

In the Commerce Setup>Order System>Layout Info> I've turned the Mini Shopping Cart switch both on and off. It doesn't work either way I have it. It does work on the store generated pages, but not in my customized pages.

So what am I missing and where?
