is the arcade directory inside of your forums directory?
ex: /usr/home/your_account/public_html/forums/arcade
or this
ex: /usr/home/your_account/public_html/arcade
if it is the latter, and the functions.php file you are talking about is in the forums/includes directory, you can do it like this:
PHP Code:
// declares the arcade image directory
$stylevar['imgdir_arcade'] = "../../arcade/images/arcade";
in the first instance, it would be like this:
PHP Code:
// declares the arcade image directory
$stylevar['imgdir_arcade'] = "../arcade/images/arcade";
I think you can also use the full path there.. but I can't remember since i haven't installed the arcadein quite sometime..
have you visited
http://www.v3arcade.com for info as well?
