VB SKIN HELP

On a vbulletin forum when you make a skin how do you make the background like wwww.bobblefmforum.co.uk rather than say habboxforum.

Basically how do you make it so when you scroll down the page the background image doesnt move/scroll aswell but only the forums

Thanks
Jake

edit the wwww.bobblefmforum.co.uk is actually www.bobblefmforum.co.uk lol

and I still need help urgently to do with this

HTML Code:

---

background-repeat:repeat-y;
background-attachment: fixed;
background-repeat: repeat;

---

I think that is it. You need to add it in the CSS where you have the image of the background

Add that code to the background box. :)
