Not sure about title... meaning not sure what you want to do with the title itself. Are we talking about calling the new window something, or do you want to alter the <title> element in the new window itself? Because I'm not sure if that can be done... url can be passed easily though... and I guess if you want to name the window itself something, you'd be doing it like so:
Make sure you pass url and title as strings when calling the function. I.e:
var pop = window.open(url, title,....blahblah......);
See how that goes for you.
