Now this works in IE but in firefox it doesn't...
the error the error console gives is
Error: divSelectCatego ry is not defined
Source File: file:///C:/Users/Administrator/Desktop/CRC/crcFAQ.html
Line: 42
Anyways hope that helps you to help me :D
Hi i think the problem may be in the line - xmlDoc.onload = readFile();
-
xmlDoc.load("XML/faq.xml");
Can you please check on this.

The problem is line 35. divSelectCatego ry hasn't been defined anywhere.
@acoder
In my html I have a div with the id divSelectCatego ry, shouldnt that mean it's defined? (new to javascript sorry)

No. You need to access it with: - document.getElementById("divSelectCategory")

Hey everyone:)
We have a critical problem, which I can see that other people also has ran
into.
In Internet Explorer 7 it is no longer possible to do a window.close after
opening a window,
without getting a alert message that ask if u want to close the window.
This did NOT happen in Internet Explorer 6, Mozilla firefox or other
browsers.
