getting an error

[dibs223]

Hi all

Sorry for being a noob here but I am facing a big problem.

I am getting an error on my web page and do not know where to start to fix it.

this is the error I am getting

Message: Object doesn't support this property or method
Line: 1
Char: 173
Code: 0

I have installed firephp, firebug and web developer.

But do not know how to use them to help me find out what the problem is.

Hope someone can help me here or point me in the right direction.

Thanks

my site is www.kaihoo.co.uk

I didn't see this error while using Firefox, on what page did you get this error, and which browser?

Sorry m8 I managed to fix that error, but still got this error which I cannot figure it out.

323 Parse Error test

and in my css file I have

}

    #mediaspace {                   
    float: left;
   width: 729px;
   padding-left: 0;
   margin-top: 0;
   margin-left: 0.0em;

}
