Links with javascript menu not working

Hi,

I have installed a blog at the following location:

http://www.thebestfurniture.com.au/blog

My problem is I use a javascript menu, which works fine from this main blog page, but when I click on a post it disappears and the links are wrong.

Could someone please tell me which file I need to alter to point the links in the menu to the correct location – I think I need to add the lines of code that call the javascript menu into another file (currently I’ve added it to header.php in my customised them which is working for the main blog page), I just don’t know which file that is?

Thanks,

Grant
