Huh? Maybe I'm just not awake this morning and not understanding what
you're trying to explain, but if you're using *radio* buttons, only
*one* of the same name can be checked at any give time. ie:
<input type="radio" name="color" value="1" /> Blue
<input type="radio" name="color" value="2" /> Red
<input type="radio" name="color" value="3" /> Black
<input type="radio" name="color" value="4" /> Green
<input type="radio" name="color" value="5" /> Mauve
If you click "Red" and "Blue" is already selected, "Blue" will
automatically be unselected. It's basic HTML.
