Hi

var e = document.forms["FORMNAME"].RADIONAME;

if(e.length != "undefined")
{
for(i=0;i<e.length;i++)
{
if(e.checked ) doSomething(e);
}
}

Or maybe

var e = document.forms["FORMNAME"].elements;
var r;
for(i=0;i<e.length;i++)
{
if(e.type == "radio")
{
r = e;// You may want to check for undefined length on some
browsers.. ( only 1 radio )
for(a=0;a<r.length;a++)
{
if(r[a].checked ) doSomething(r[a]);
}
}
}
