here is the javascript code

<script language="JavaScript">

var newWindow = null;

function closeWin(){
    if (newWindow != null){
        if(!newWindow.closed)
            newWindow.close();
    }
}

function popUpWin(url, type, strWidth, strHeight){
    
    closeWin();
    
    if (type == "fullScreen"){
        strWidth = screen.availWidth - 10;
        strHeight = screen.availHeight - 160;
    }
    
    var tools="";
    if (type == "standard" || type == "fullScreen") tools = "resizable,toolbar=yes,location=yes,scrollbars=yes,menubar=yes,width="+strWidth+",height="+strHeight+",top=0,left=0";
    if (type == "console") tools = "resizable,toolbar=no,location=no,scrollbars=no,width="+strWidth+",height="+strHeight+",left=0,top=0";
    newWindow = window.open(url, 'newWin', tools);
    newWindow.focus();
}
</script>

and here is the link you can use to use that code

<a href="http://notmine.com" target="popUpWin" onclick="popUpWin(this.href,'console',400,600);return false;">Trial</a>

can someone edit the code so it has the scrollbar (the one on the side of the page) so people can scroll down.

You should simple change scrollbars=no into scrollbars=yes - you will enable both scrollbars - there's no possibility (as far as I am concerned) to enable only one of them.

Absolutely what he said is correct just change it scrollbars=yes
you can get it immediately...
Got it ?

yes i have done it
