Как поправить немного javascript?

time_to_x_hour = false;
function PremierTimer(premiere_date)

	{

	}
	if(time_to_x_hour<=0) {
		if(document.getElementById('CountdownClockDiv'))
		document.getElementById('CountdownClockDiv').style.display="none";
		document.getElementById('CountdownClock').innerHTML=""; return;
	}
	var daysleft = parseInt(time_to_x_hour/(24*60*60));

	if (daysleft < 0) daysleft=0;
	var d = daysleft - Math.floor(daysleft/10)*10;
	var dd=0;
	if (daysleft > 100) dd=daysleft-Math.floor(daysleft/100)*100;
	var daysleftFinal;
	var text_day;
	if (d==1 && daysleft!=11 && dd!=11) text_day="день";

	if (daysleft > 0) daysleftFinal = '<span class="daysLeft">' + daysleft + '&nbsp;' + text_day + '</span><span class="timeLeft">+';  
	else daysleftFinal = '';
