//STEP 2: Change the two text below to reflect the occasion, and message to display on that occasion, respectively
var occasion="Release Of the GoF DVD"
var message_on_occasion="The Gof DVD Is Out! Go And Get It!"

//STEP 3: Configure the below 5 variables to set the width, height, background color, and text style of the countdown area
var countdownwidth='338px'
var countdownheight='105px'
var countdownbgcolor='lightblue'
var opentags='<font face="Verdana"><small>'
var closetags='</small></font>'
