Answer 1

I think you need to use checkboxlist for that, as your current choice is not correct..

Edit:

To restrict, user can select only 1 item, use this javascript ..

 <script language="javascript" type="text/javascript">
    function UnSelect(id) {
        var frm = document.forms[0];

        for (i = 0; i < frm.elements.length; i++) {
            if (frm.elements[i].type == "checkbox") {
            if(frm.elements[i] != document.getElementById(id))
            {
                frm.elements[i].checked = false;
                }
            }
        }
    }
</script>

<input type="radio" name="foo" value="bar" onclick="Toggle(this);">

var radios = new Array;
function Toggle(radio) 
{
    if (radios[radio.name] == radio.value) 
    {
        radio.checked = false;
    }
    else 
    {
        radio.checked = true;
        radios[radio.name] = radio.value;
    }
}
