I don't use cfform but something like this would work...
<script language="javascript">
function chk()
{
var cont = false;
radio = document.getElementsByName("age_id");
for(var i = 0; i < radio.length; i++) {
if (radio[i].checked == true) {
cont = true;
break;
}
}
if (cont == false) {
// notify user
alert("nada was checked");
}
return cont;
}
</script>
<form name="foo" action="frm.cfm" method="post" onsubmit="return chk();">
age : <br />
<input type="radio" name="age_id" value="1"> 18-25<br />
<input type="radio" name="age_id" value="2"> 26-33<br />
<input type="radio" name="age_id" value="3"> 33-40<br />
<input type="radio" name="age_id" value="0"> other<br />
<input type="submit">
</form>
but being javascript I'd check server side too...
