<script>
cookiename="quiz";
function submitCookie()
{
SetCookie (cookiename,document.quiz.scorefield.value);
location = "datapage.html";
}

</script>

<form name = quiz
action = "Javascript: submitCookie()" >
<body>

<script>

var questions = new Array();

var score = 0;

function checkanswers()
{

score = 0;
for (var i = 1; i <questions.length; i++)
{
if (document.quiz["answer" + i].value == rightanswers[i])
score++;
}
document.quiz.scorefield.value = score + "/" + (questions.length-1);
}
</script>

<script>

for ( i = 1; i < questions.length; i++)
{


document.write ("<p>");
document.write (questions [i]);
document.write ("<p>");

document.write ("<select name = answer" + i + ">");
document.write ("<option value = 0>Choose...</option>");

document.write ("<option value = 1>" + answerone[i] + "</option>");
document.write ("<option value = 2>" + answertwo[i] + "</option>");
document.write ("<option value = 3>" + answerthree[i] + "</option>");


document.write ("</select>");
}

</script>

<p>

First of all, let me start by saying this will be way easier with a serverside language like PHP, however, that is not the answer to your question.

Now, onto your question.
- Do you get javascript errors? If so, post them here
- I assume you've tried if your SetCookie and GetCookie functions are correct (by for example setting and immediately getting the same cookie in one page)? If not, try it (i can't check those functions for you, because you use an external file, and you didn't post it)
- Have you checked that both cookiename and document.quiz.scorefield.value contain the desired information. Maybe adding a line "alert(cookiename+'\n'+document.quiz.scorefield.value);" at the top of your submitCookie function will show if those values are correct.

Another thing: you should use <script type="application/x-javascript" src="pd-cookie-functions.js"> instead of the language="whatever" thing.

Also, please post your HTML/javascript between [code] tags, it's much easier to read.

Hi again,thanks for replying. i added the alert to my setcookie function and nothing happened...

heres my external file:

[code]

/* Code from chapter 7 */
/* Beginning of Cookie Code Based on code by Bill Dortch
of hidaho designs who has generously placed it in the public domain.*/
function SetCookie(name,value,expires,path,domain,secure){
var temp = name + "=" + escape(value);
if (expires){
temp += "; expires=" + expires.toGMTString();
}
if (path){
temp += "; path=" + path;
}
if (domain){
temp += "; domain=" + domain;
}
if (secure){
temp += "; secure";
}
document.cookie = temp;
}
function GetCookie(name){
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i,j) == arg){
return getCookieVal(j);
}
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function getCookieVal(offset){
var endstr = document.cookie.indexOf(";", offset);
if (endstr == -1){
endstr = document.cookie.length;
}
return unescape(document.cookie.substring(offset,endstr));
}
function DeleteCookie (name,path,domain) {
if (GetCookie(name)) {
var temp = name + "=";
temp += ((path) ? "; path=" + path : "");
temp += ((domain) ? "; domain=" + domain : "");
temp += "; expires=Thu, 01-Jan-70 00:00:01 GMT";
document.cookie = temp;
}
}
/* End of Cookie Code */

/* converts days to milliseconds */
function daysToMS(days){
return days * 24 * 60 * 60 * 1000;
}

/* converts weeks to milliseconds */
function weeksToMS(weeks){
return weeks * 7 * 24 * 60 * 60 * 1000;
}

/* converts years to milliseconds */
function yearsToMS(years){
return years * 365.25 * 24 * 60 * 60 * 1000;
}
/* End of code from chapter 7 */

im not getting any errors either? the "store score" button does nothing

This is how you should use code tags :rolleyes:
Anyways, if you don't get an alert as suspected, somewhere along the lines there is an error.

If you don't have it, i suggest you download Firefox (it's a good browser anyways), and try your page in that. Then look at the javascript console. It should tell you where errors occured, giving you the line number of the error code to look at.

NOTE: I think i see the error. you have this:

<input type = "button" value = "Store Score" = onclick="submitCookie()">

You forgot the semicolon.
