Hi Guys. Im currently working on a code that makes use of Javascript and XML DOM. The open-win() function is working perfectly fine and pops up a new window when called. But the problem is that im not able to call dispval() function from within the open_win() function using the onclick event of the button. I have highlighted it. Thanks in advance.

{
if (window.ActiveXObject)
{
var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
}
if (document.implementation.createDocument)
{
xmlDoc=document.implementation.createDocument("","",null);
}
nwin=window.open("","assign","height=500,width=800");
xmlDoc.async=false;
var loaded=xmlDoc.load("a.xml");
var tit=xmlDoc.getElementsByTagName("title");
nwin.document.write("<h3><p align='center'>A New York Times Blog</p></h3>");
nwin.document.write("<form name='main'><select name='articles' id='artid'>");
nwin.document.write("<option selected='selected'>Choose an Article</option>");
for (i=1;i<tit.length;i++)
