XMLHTTP is not working with Firefox

[Deanorezo]

this is killing me. It works fine with IE but nothing with Firefox. Can anyone help please
it should grab text from klm2 and the response should print to klm3

<script>
function PostOrder() 
{ 
var done1;
   var xmlhttp = new XMLHttpRequest();   strPOSTURL="http://localhost/server/MYDLL.asp"
   xmlhttp.Open("POST", strPOSTURL, false); 
  xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
   xmlhttp.Send(document.getElementById("klm2").value); 
   done1=xmlhttp.responseText; 
   document.getElementById("klm3").value=done1.replace(/<(?:.|\n)*?>/gm, '');
 
} 
</script> <textarea name=klm3 id="klm2" rows=10 cols=115>THIS IS A TEST<br> <textarea name=klm3 id="klm3" rows=25 cols=115>

JS is case-sensitive, so the XHR methods should be open() and send().

also check the Error Console for further issues.
