Need Help with starting a timer in Javascript

Hi All I have two pages Timer.jsp and Questions.jsp The codes are given below timer .jsp=

function Tick() {
        if (TotalSeconds <= 0) {
                alert("Time's up!")
                return;
        }

TotalSeconds -= 1;
        UpdateTimer()
        window.setTimeout("Tick()", 1000);
}
function UpdateTimer() {
        var Seconds = TotalSeconds;
        
        var Days = Math.floor(Seconds / 86400);
        Seconds -= Days * 86400;

var Hours = Math.floor(Seconds / 3600);
        Seconds -= Hours * (3600);

var Minutes = Math.floor(Seconds / 60);
        Seconds -= Minutes * (60);

var TimeStr = ((Days > 0) ? Days + " days " : "") + LeadingZero(Hours) + 
		":" + LeadingZero(Minutes) + ":" + LeadingZero(Seconds)

Timer.innerHTML = TimeStr;
}

function LeadingZero(Time) {

return (Time < 10) ? "0" + Time : + Time;

}

Now i want when i click on the starttest button on timer.jsp it takes me to Questions.jsp which it does and starts a countdown timer there for 30:00 munites this is where i need help . This is a project i am doing please if anybody can help.

It should be like the website http://www.indiabix.com/online-test/java-programming-test/61 . In this website when you clik on starttest button where it redirects to another page and starts the timer on the left hand side of the page . Please if anybody can help it would be of great help to me

How is this question different from your last one? What is the point of having JavaScript in timer.jsp if that page isn't even loaded when you want the timer to be running?
