How to validate when option 4 is selected in radio button and duration is selected in another option button.

[sandy1028]

This code is working for all radio button when duration option is selected.
I just want when only 4th radio button is selected i.e when value =4.

for (var i=0; i < document.example.opt2.length; i++)
   {
   if (document.example.opt2[i].checked && document.example.opt2[i].value==4 && document.example.date2.value != "yyyy-mm-dd"))

  {
   var msg="select only Start date, duration option not available";
          alert(msg);
          return false;

  }
   }

Can really find anything off. How about splitting it like this:

for (i=0;i<document.example.opt2.length;i++){
  if (document.example.opt2[i].checked==true)
    theselectedone=i;
  }

if(document.example.opt2[theselectedone].value == 4 && document.example.date2.value != "yyyy-mm-dd")
  {       

var msg="select only Start date, duration option not available";
              alert(msg);
              return false;
}
