New sized window help

I have this javascript:<html>
<head>

<script type=“text/javascript”>

{
window.open(“http://www.w3schools.com”,“my_new_window”,“toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=yes, width=350, height=250”)
}
</script>

</head>
<body>

I am using it to make a window that is a certain size but when I preview it in Dreamweaver, it opens a blank page, then opens this little pop-up thing. I want it just to have the pop-up, not the blank page.

-Thanks!!!
