    radio button validation

    I have an mysql array with several radio buttons,

    <INPUT name="bookout" id="bookout" type="radio" class="formslova" value='value1'>
    <INPUT name="bookout" id="bookout" type="radio" class="formslova" value='value2'>
    <INPUT name="bookout" id="bookout" type="radio" class="formslova" value='value3'>

    I want to make a button validation:

    if (document.getElementById("bookout").checked==false) {

    For some reason when I have more that one button in the array only the first counts, meaning only when first is clicked is the button validation checked=true.

    all your radio button has same id, which is incorrect, that is why your validation fails.
    you have to change the id for your radio button and that should work

    Yup -- change or remove the ID on the buttons. It'll probably easiest to validate using a reference to the form:

    HTML Code:
    var form = document.getElementById('form_id');
    if (!form.radio_group_name) {
      // alert the user somehow
    ... or something along those lines. And remember that client-side validation is not sufficient in itself! Check everything server-side as well.

    I agree with Apple. Flash is just terrible.

    Use CODE tags!
