Multiple groups of radio buttons validation

[mkronix]

Hi guys,

I have a form with input text, dropdown menu and groups of radio button. The validation for input text and dropdown menu works fine with these js validator :

<script language="JavaScript">
function formValidator(){

// Make quick references to our fields

 var pensyarah = document.getElementById('pensyarah');
 var kksem = document.getElementById('kksem');



 // Check each input in the order that it appears in the form!
if(madeSelection(pensyarah, "Sila pilih Pensyarah")){
 if(madeSelection(kksem, "Sila pilih Kod kursus")){



 return true;
 }
 }


 return false;

}



function isEmpty(elem, helperMsg){
 if(elem.value.length == 0){
  alert(helperMsg);
  elem.focus(); // set the focus to this input
  return true;
 }
 return false;
}

function isNumeric(elem, helperMsg){
 var numericExpression = /^[0-9\s\:]+$/;
 if(elem.value.match(numericExpression)){
  return true;
 }else{
  alert(helperMsg);
  elem.focus();
  return false;
 }
}

function isAlphabet(elem, helperMsg){
 var alphaExp = /^[a-zA-Z\s\.]+$/;
 if(elem.value.match(alphaExp)){
  return true;
 }else{
  alert(helperMsg);
  elem.focus();
  return false;
 }
}

function isAlphanumeric(elem, helperMsg){
 var alphaExp = /^[0-9a-zA-Z\s]+$/;
 if(elem.value.match(alphaExp)){
  return true;
 }else{
  alert(helperMsg);
  elem.focus();
  return false;
 }
}

function madeSelection(elem, helperMsg){
 if(elem.value == "*Tiada Pilihan"){
  alert(helperMsg);
  elem.focus();
  return false;
 }else{
  return true;
 }
}


function emailValidator(elem, helperMsg){
 var emailExp = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/;
 if(elem.value.match(emailExp)){
  return true;
 }else{
  alert(helperMsg);
  elem.focus();
  return false;
 }
}


</script>

the problem is, how to add the groups of radio button validation script inside the existing js validator.. is it posible to merge it in one function? I try to add this code but the function its not working at all...

                                    var flag1 = 1;

                                    if (document.thisform.qs1.type == "textarea")
                                    {
                                        if (document.thisform.qs1.value)
                                        {
                                            flag1 = 0;
                                        }
                                    }
                                    else
                                    {
