Adding Javascript to Page?

I am currently trying to add the following Javascript into one of my Pages, it is not showing up. If I put the Javascript into my sidebar it works perfectly fine. I just do not want to put it into my sidebar, I want it to work on one of my Pages.

The script I am trying to use is this:

<SCRIPT LANGUAGE="JAVASCRIPT">
			today = new Date();
			BigDay = new Date("July 15, 2011")
			msPerDay = 24 * 60 * 60 * 1000 ;
			timeLeft = (BigDay.getTime() - today.getTime());
			e_daysLeft = timeLeft / msPerDay;
			daysLeft = Math.floor(e_daysLeft);
			e_hrsLeft = (e_daysLeft - daysLeft)*24;
			hrsLeft = Math.floor(e_hrsLeft);
			minsLeft = Math.floor((e_hrsLeft - hrsLeft)*60);
			document.write(daysLeft + " days");
			</SCRIPT>

Any suggestions on how I can get this to show up?
