I know how to write cookies in JavaScript

//Create the cookies
        document.cookie = "Name=" + Name + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
        document.cookie = "Surname=" + Surname + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
        document.cookie = "Number=" + Number + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
        document.cookie = "Email=" + Email + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
        document.cookie = "Country=" + Country + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
        document.cookie = "Company=" + Company + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
        document.cookie = "Title=" + Job + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";

But how can I read each one of them in JavaScript because I want to populate the text boxes next time the user come to the form?

I have tried this but it does not work............

var cookieName = ReadCookie("Name");
document.getElementById('txtName').value = cookieName;

Thanks in advanced!!
