Here is an instance that's common and not unique for "name":

<input type="radio" name="pizza" value="sausage" />
<input type="radio" name="pizza" value="pepperoni" />
<input type="radio" name="pizza" value="cheese" />

If you have the option (and if it's needed), assign an id to each input - this will ensure that you're getting the correct element.

Hope that helps.

"innerHTML is a string. The DOM is not a string, it's a hierarchal object structure. Shoving a string into an object is impure and similar to wrapping a spaghetti noodle around an orange and calling it lunch."
