[Plugin: PerformerJS] Popper just opens another tab – doesn’t “pop”

I’m on WP 2.9.1 using a Woo Theme. You can see it here:

Scroll down to the bottom and click on the Facebook icon. I want that to be a popper window so the user doesn’t have to leave the site, but it opens an entirely new tab, no matter what I do. ‘

Here’s the link code I’m using (below). Basically, I just copied your code from the documentation example, and subbed in my link. When that didn’t work right, I added the targetName parameter that you mention as required in your documentation. Doesn’t “pop” either way – always opens a new tab.

Suggestions?
