Help: Javascript not working in Firefox "event not defined"

[Wiseman]

Hello,

I am making a web page and have included a JavaScript named crazy clock. The
page displays fine in IE but not in Firefox. The event console says: "event
is not defined" at line 143. According to notepad plus, line 143 is:

ymouse =
(ns)?evnt.pageY +ClockFromMouse Y-(window.pageYOf fset):event.y+C lockFromMouseY;

And the whole function is:

function Mouse(evnt){
ymouse =
(ns)?evnt.pageY +ClockFromMouse Y-(window.pageYOf fset):event.y+C lockFromMouseY;
xmouse = (ns)?evnt.pageX +ClockFromMouse X:event.x+Clock FromMouseX;
}

I am new to javascript and would be grateful if somebody told me how to
solve this problem.

Regards.

It means that however the value of - ns - is defined its value is not
a useful discriminator of web browsers. That is, it is still false on
Friefox. A better subject for the test would be the - evnt - formal
parameter, as that has a direct relationship with the ability to use
an event object passed as an argument to the function.
