  2. hi,

    thanks for coding tip. but I've noticed something.
    If you add a new radio group the value stays the one of the first group or perhaps i do something wrong
    var number = $("input[@name=numbers]:checked").val();
    alert(number);
    var number2 = $("input[@name=numbers2]:checked").val();
    alert(number2);

  3. I get the same behaviour... i.e. only works on the first radio button group. Any idea how to get the second button group?
