it is exactly that you did not take the = sign into account!
here is a basic function i made to get simple cookie information!


function getCookieData(whatCookie){
    var myCookie = new String(document.cookie);
    var myCookieHeader = whatCookie+"=";
    var myCookieStart = myCookie.indexOf(myCookieHeader);
    var myCookieEnd = myCookie.indexOf(';',myCookieStart);

    // if there is only one cokie you do not have the semicolon at the end
    if (myCookieEnd == -1){
        myCookieEnd = myCookie.length;
    }
    // extract data and check if the cookie exist
    if( myCookie.indexOf(myCookieHeader) != -1){
        myCookieStart = myCookieHeader.length;
        return myCookie.substring(myCookieStart, myCookieEnd);
        }
    else{
        // if the cookie does not exist well ... do what ever you want
        return 'noCookie';
    }
}

have fun!
