JavaScript Error in Netscape document.getElementsByTagName

I need help trouble shooting the below script in netscape. It seems to work with IE 5+ and Opera. But it does not work in Netscape 4.x I am getting document.getElementsByTagName is not a function error when submit is pressed in Netscape.
Please help. Thanks ahead.


<script type="text/javascript">function getRadio(radioName){
 var ret = null;
 var inputs = document.getElementsByTagName('input');
 for(var i = 0; i < inputs.length; i++){
  if(inputs[i].type.toLowerCase() == 'radio'){
   if(inputs[i].name == radioName && inputs[i].checked){
    ret = inputs[i].value;
   }
  }
 }
 return ret;
}
</script>
</head><body>
 <form method="post" onsubmit="location.href = getRadio('test1'); return false;"> 
 <input type="radio" name="test1" value="http://www.yahoo.com" checked>A
 <input type="radio" name="test1" value="http://www.google.com">B
 <P>
 <input name="submit" type="image" value="submit">

</form>
<form method="post" onsubmit="location.href = getRadio('test2'); return false;"> 
 <input type="radio" name="test2" value="http://www.cnn.com" checked>A
 <input type="radio" name="test2" value="http://www.web.com">B
 <P>
