Redirect By Cookie

[TimFA]

I found this script:

External:

// Redirect Cookie 2
// Version 1.10
// Written by Chris Hansen.
// Copyright © 1999-2003 by Chris Hansen.

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 "";
}

function SetCookie(name, value){
  expDays = 365;
  exp = new Date();
  exp.setTime(exp.getTime() + (expDays * 24 * 60 * 60 * 1000));

  document.cookie = name + "=" + escape(value) + "; expires=" + exp.toGMTString();
}

function cRedirect(value){
  SetCookie("cChoise", value);
}

function IsCookieSet()
{
  var redirpage = GetCookie("cChoise");
  if (redirpage != "") {window.location = redirpage;}
}

Head:

function menuRedirect(){
    var select = eval(document.redirectForm.elements[0].selectedIndex);
    var choise1 = "choise1.html";
    var choise2 = "default/index.html";

    if (select==0) void(0);
    else if (select==1) {window.open(choise1,"_top"); cRedirect(choise1);}
    else if (select==2) {window.open(choise2,"_top"); cRedirect(choise2);}
  }

Menu:

    <FORM name="redirectForm">
      <TABLE border="1" cellspacing="0" cellpadding="0">
        <TR>
          <TD>
            <SELECT name="menu" onChange="menuRedirect()">
              <OPTION value="1">Make A Choise</OPTION>
              <OPTION value="2">Choise 1</OPTION>
              <OPTION value="3">Choise 2</OPTION>
            </SELECT>
          </TD>
        </TR>
      </TABLE>
    </FORM>

I've found 2 problems, 1 if I try to change anything, the cookie part (top) has to be removed otherwise nothing happens, I suspect theres an ID I'm missing and not changing, but thats minor. For some reason, whenever I run that in my browser it doesn't remember after a close. I looked it over and tried changing a few things, but no luck.

This is what the code in the head should be. Notice the onload event is the only change

function menuRedirect(){
    var select = eval(document.redirectForm.elements[0].selectedIndex);
    var choise1 = "choise1.html";
    var choise2 = "default/index.html";

    if (select==0) void(0);
    else if (select==1) {window.open(choise1,"_top"); cRedirect(choise1);}
    else if (select==2) {window.open(choise2,"_top"); cRedirect(choise2);}
  }
window.onload=IsCookieSet;
