Få bort alert medelande?

Jag ska använda detta script på min sida.. (tabber menu)
http://www.barelyfitz.com/projects/tabber/example-cookies.html

Men om ni går in och testar scriptet så får man ett alert medelande.. och jag skulle vilja få hjälp om hur man får bort det..

/*==================================================
  Set the tabber options (must do this before including tabber.js)
  ==================================================*/
var tabberOptions = {

  'cookie':"tabber", /* Name to use for the cookie */

  'onLoad': function(argsObj)
  {
    var t = argsObj.tabber;
    var i;

    /* Optional: Add the id of the tabber to the cookie name to allow
       for multiple tabber interfaces on the site.  If you have
       multiple tabber interfaces (even on different pages) I suggest
       setting a unique id on each one, to avoid having the cookie set
       the wrong tab.
    */
    if (t.id) {
      t.cookie = t.id + t.cookie;
    }

    /* If a cookie was previously set, restore the active tab */
    i = parseInt(getCookie(t.cookie));
    if (isNaN(i)) { return; }
    t.tabShow(i);
    [red]//alert('getCookie(' + t.cookie + ') = ' + i);[/red]
  },

  'onClick':function(argsObj)
  {
    var c = argsObj.tabber.cookie;
    var i = argsObj.index;
    [red]//alert('setCookie(' + c + ',' + i + ')');[/red]
    setCookie(c, i);
  }
};
