I've been working on this one for a few hours...and i'm just not sure how to do it. I need to configure the path of the variable(s)

// Path to user files relative to the document root.
$Config['UserFilesPath'] =;

// Fill the following value it you prefer to specify the absolute path for the
// user files directory. Useful if you are using a virtual directory, symbolic
// link or alias. Examples: 'C:\\MySite\\userfiles\\' or '/root/mysite/userfiles/'.
// Attention: The above 'UserFilesPath' must point to the same directory.
$Config['UserFilesAbsolutePath'] = '' ;
