Cookies, window.open, and more

I had posted previously about passing js generated vars via a query string. It's become very apparent that this is not possible. So, I'm now trying to accomplish the mission by sending the vars via cookie. Ok, that will work, but I have a different problem now. Please take a look at the code below and tell me: Why doesn't the window open?

function kick(eid) {
	var exdate=new Date();
	exdate.setDate(exdate.getDate()+1);
	document.cookie=eid+ "=" +escape(eid)+("" : ";expires="+exdate.toGMTString());
	document.cookie=xco+ "=" +escape(xco())+("" : ";expires="+exdate.toGMTString());
	document.cookie=yco+ "=" +escape(yco())+("" : ";expires="+exdate.toGMTString());
	window.open("/execute/j_input.php","j_input","menubar=no,width=100,height=100,toolbar=no,scrollbars=no,status=no,resizable=no");
}

Code (markup):

I'm calling that function like this:

<div id="drag" class="postit" style="top:135px;left:135px" onmouseup="kick(1)">

HTML:

I'm not even sure if the cookies are set properly. If I can get the window to open it will tell me what's going on and I can work from there. Any insight would be appreciated.

 

The function errors out on:

document.cookie=eid+ "=" +escape(eid)+("" : ";expires="+exdate.toGMTString());

try:

document.cookie=eid+ "=" +escape(eid)+";expires="+exdate.toGMTString();

Also I recommend firefox with web developer toolbar and firebug to see where javascript is erroring out.

Good luck
