Radio buttons are very hard to code this way. A cluster of buttons has
a single name, but each button is a separate input element in the DOM,
and no two elements may have the same ID, so there's no way to have a
1:1 mapping like this.
My usual pattern looks like this:
<label for="elmName">Radio Group</label>
<span id="elmName">
<input type="radio" name="elmName" value="foo" id="elmName_foo"
checked="checked" />
<input type="radio" name="elmName" value="bar" id="elmName_bar" />
<input type="radio" name="elmName" value="baz" id="elmName_baz" />
<input type="radio" name="elmName" value="blah" id="elmName_blah" />
</span>
To get ahold of the radio elements inside your function, try
$('elmName').select('input') --> returns an array of the radio buttons
with all the iterator goodies attached
