    Hi Guys,

    im trying to validate a form for xhtml and one of the errors coming up a lot is ID "whatever" already defined. How do i get around this as in the case of radio buttons the id is the same for the yes and no states. I thought the id for them had to be the same for the radio button to work correctly?

    Thanks

    No it's name that has to match not the id.

    The ID attributes need to be unique for each HTML element on a page

    If you using ID to reference multiple elements on a page you will fail XHTML, however you can use "class" instead of "id" and that should work fine.

    The class is just for the style though.

    The specification should really include a "group" attribute - while "name" is the correct way to group them, I don't think it's all that intuitive in this instance.
