I have a cookie that sets the colour on the homepage when you click on an option, the page turns blue then if you click a hyperlink to another part of the website that page also changes colour(Good So Far) if you then change colour on this page and return to the previous one the previous one still has its original colour how do i solve this here is my cookie script

<script type="text/javascript"><!--
function getCookieVal (offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}

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 SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
// -->
</script>

a better way than to send cookies for this operation would be to use the titlebar.
About 20% of people disable cookie support from their browser due to secuirty concerns.

Use the titlebar such as <a href="newPage.html?colour=blue">Click Me</a>

The "?colour=blue" part can be retrieved from the page just opened i.e. newPage.html
by using the window.search property.
