[Javascript] Quiz Script Mac IE 5.22 Problem

[Humberto T. Reyes]

Greetings,

I am currently using a script for a training quiz below--the problem I 
am having is that on IE 5.22 It always provides the incorrect alert, 
even if the answer id correct.  The answer is collected as a variable 
from the form that submits to this script.

Does anyone see anything wrong with this script?  Any ideas.

Thanks in advance.

Humberto

function exam(examform, next) {
	var noquizckbx = document.getElementsByName('noquiz')[0];
	if (noquizckbx) {

if(answer.length == 0) {
document.location.href = next;

newgrade = new Array(answer.length);
for (i=0; i<examform.elements.length; i++) {

incorrect = 0;

incorrect = 1;

if (incorrect==0) {
//   alert('Correct.  Continuing to next page');
document.location.href = next;
} else {
alert('Incorrect.  Please try another answer');

function answerquiz(examform) {

//		alert('here:'+formvar.name+formvar.value+'='+answer[formvar.name]);
				if (formvar.value == answer[formvar.name]) {
					formvar.checked = 1;
	    formvar.value = answer[formvar.name];
