In accessing radio button using javascript, it must be searched first on which boxed is checked to get the value.

 
/* Language : Ecma a.k.a. Javascript */
 
function get_radio_value(){
var oRadio=document.form_name.radio_name;
    for (i=0;i<oRadio.length;i++) {
     if (oRadio[i].checked) {
	  radio_value = oRadio[i].value;
     }
    }
}
