browser button cart clear creates credit demos don front installed javascript needed options page pop-up processing shopping show view wasn window working

I just installed the shopping cart button and rather than creating a pop-up, it creates a new window in the browser.

How do I get it to work like the demos on the front page?

Also, I don't see the credit card processing options show up.

N/M: It wasn't clear that to get the javascript pop-up working the "view cart" button needed to be there as well.
