MM_validateForm() and radio buttons

I'm using a dreamweaver java fuction to validate fields in a form, but it only seems to work with text fields.

This is the function:

function MM_validateForm() { //v4.0
var i,p,q,nm,test,num,min,max,errors='',args=MM_valida teForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=MM_findObj(args[i]);
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an e-mail address.n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' must contain a number.n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min || max<num) errors+='- '+nm+' must contain a number between '+min+' and '+max+'.n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is required.n'; }
} if (errors) alert('The following error(s) occurred:n'+errors);
document.MM_returnValue = (errors == '');
}

In the form, it goes like this:

<form onSubmit="MM_validateForm('nombre','','R','apellidos','','R' ,'email','','RisEmail','edad','','RisNum','estatur a','','RisNum','peso','','RisNum');return document.MM_returnValue">

I want to know how can I modify this function to use it also to validate radio buttons.

Thanks a lot...
