Age Varification Help!

Hi. I have copied a Age Varification code off this website (http://www.rockstargames.com/vicecitystories/), and I have edited it to make the following code. However, each time I enter my age (19), it re-directs me to the "noentry" page, instead of "index_2".

CODE FOR THE HEADER:

<script language="JavaScript" type="text/JavaScript">
<!--

var expireDate = new Date();
var year = expireDate.getYear();
year = (year < 1900) ? year + 1900 : year;
expireDate.setYear(year + 3);

function cookieChck() {
var allcookies = document.cookie;
var detectCookie = allcookies.indexOf("index");

if (detectCookie != -1) {

var start = detectCookie + 19; //start of cookie value
var end = allcookies.indexOf(";",start); //end of cookie value

if (end==-1) end = allcookies.length;

var userAge = allcookies.substring(start,end); //extract the

birthdate
userAge = unescape(userAge); //decode value

var age = new Date(userAge);
//check if over 17
if (over17(age)){
location.replace("index2.html"); }
else
{
location.replace("noentry.html");
}
}
else {checkDate();}
}

//creates a cookie with the values passed in
function my_setCookie(nam, val, expire, domain, path) {
var cookie_str = "";
cookie_str += nam + "=" + escape(val);
//cookie_str += "; domain=" + domain;//deleted because the cookie wasn't
//cookie_str += "; path=" + path; //getting detected and they're not

needed
cookie_str += "; expires=" + expire.toGMTString();
document.cookie = cookie_str;
};

function setCookie() {
//if the date is valid, create a cookie
var user_age = new Date();

user_age.setMonth(document.ValidForm.birthmonth.options

[document.ValidForm.birthmonth.selectedIndex].value-1);
user_age.setDate(document.ValidForm.birthday.options

[document.ValidForm.birthday.selectedIndex].value);
user_age.setFullYear(document.ValidForm.birthyear.options

[document.ValidForm.birthyear.selectedIndex].value);

my_setCookie("index", user_age.toUTCString() , expireDate,

".rockstargames.com", "/");
}

function over17(age) {
var ageDate = new Date();
var ageYear = ageDate.getFullYear()-17;
ageDate.setFullYear(ageYear);
if (age <= ageDate) {return true;}
else {return false;}
}

function checkDate() {
var age = new Date();
age.setMonth(document.ValidForm.birthmonth.options

[document.ValidForm.birthmonth.selectedIndex].value-1);
age.setDate(document.ValidForm.birthday.options

[document.ValidForm.birthday.selectedIndex].value);
age.setYear(document.ValidForm.birthyear.options

[document.ValidForm.birthyear.selectedIndex].value);

if ((document.ValidForm.birthday.options

[document.ValidForm.birthday.selectedIndex].value != 0) &&

(document.ValidForm.birthmonth.options

[document.ValidForm.birthmonth.selectedIndex].value !=0) &&

(document.ValidForm.birthyear.options

[document.ValidForm.birthyear.selectedIndex].value != 0))
{
setCookie();

if (over17(age)){
location.replace("gtavcs.html"); }
else
{
location.replace("noentry.html");
}
}
}
//-->

thanks, it has improved it to an extent that it doesnt go to the "noentry" page, but it still doesn't advance to the "index2" or the "noentry" if i make the date under 18.

Sorry, the names of your variables are a bit confusing.

See new version above.

This checks that the user is over 17 using milliseconds (i.e not just the year)

thanks, but it still doesnt advance to any other page
