Radio Buttons/Option Group

How do I get radio buttons to work in HTML, so that only one in a group can
be selected at a time? How do I get the value returned from them? How do I
reference them in JavaScript? What value is returned?

Muchos Gracias.

Give them all the same name.

How do I get the value returned from them?

Include the appropriate URI in the action attribute of the form.

How do I reference them in JavaScript?

document.forms[i].elements[i]
or
document.formname.elementname
or
document.getElementById("id")

What value is returned?

name=value

So,
<input type="radio" name="cheese" value="cheddar">
<input type="radio" name="cheese" value="stilton
<input type="radio" name="cheese" value="brie">
<input type="radio" name="cheese" value="roquefort">

Will on submission of the form return cheese=stilton if the second
radio button is selected.
