Creating a new window

Brennon Bortz's icon

I can't, for the life of me, figure out how to create a new window with Javascript (nor can I find any other posts about it...except mine). I posted on this a while ago, and have never received any responses:

As I show, I believe I've followed the documentation to the T, but I certainly could be missing something. I'm not averse to an alternate solution to my current problem, but dynamically creating a new window would CERTAINLY be my first choice. Anyone have any ideas?

Thanks!
