//Specify display mode. 3 possible values are:
//1) "always"- This makes the fade-in box load each time the page is displayed
//2) "oncepersession"- This uses cookies to display the fade-in box only once per browser session
//3) integer (ie: 5)- Finally, you can specify an integer to display the box randomly via a frequency of 1/integer...
// For example, 2 would display the box about (1/2) 50% of the time the page loads.

var displaymode="always"

var autohidebox=["no"] //Automatically hide box after x seconds? [yes/no, if_yes_hide_after_seconds]

var IEfadelength=1 //fade in duration for IE, in seconds
var Mozfadedegree=0.05 //fade in degree for NS6+ (number between 0 and 1. Recommended max: 0.2)

////////No need to edit beyond here///////////
