your code should look something like this, I am using a button here but the same could be done on a link
<input type="button" onClick="javascript:window.open('pageToopen')">
this is one way but i normally use something like this as it is more customizable:
<html>
<head>
<title>open window</title>
<script language="javascript">
<!--
var desktop;
function openWindow(url,w,h){
if (desktop && desktop.location) desktop.close();
desktop = window.open(url, "_blank","toolbar=0,location=0,directories=0,status=0,menubar=1,scrollbars=1,resizable=1,width="+w+",height="+h);
}
//-->
</script>
</head>
<body>
<a href="javascript

penWindow('yourpagehere','width','height')">Open a window</A>
</body>
</html>
this uses a bit of javascript (openWindow function) that i pass three params to (page to open, width of window, height of window) when the link is clicked the page will open with the various options that you set in the function (scrollbars, menus etc) at the moment they are set to being on (1=on !)
hope this helps !
