Loading variable with url syntax query

Hi there could someone please help me
I trying to load a variable with a url string.

link = "http://imagical.kol.co.nz/pages/Me_B.html", "_top";

It works but it doesn't load in seperate window.
I think this is because the variable link is only holding the string inside the first set of quotation marks and does not see the second string "_top"

I tried to put braces around but I get a sandbox violation error.
link = ("http://imagical.kol.co.nz/pages/Me_B.html", "_top");

Looking forward to any ideas on the right syntax to use
Thanks

PHP Code:

---

link = "http://imagical.kol.co.nz/pages/Me_B.html, _top";
arr = link.split(",");
getURL(arr[0],arr[1]);
